Supply

Question: How to create a supply and demand graph? Draw supply and demand graphs that estimate what will happen to demand, supply, and the equilibrium price of pizza if the following events occur: 1. Consumer income declines. How do I create a supply and demand graph in Excel?

Answer: In excel, make three columns of information like this: (blank) SupplyDemand 101060 202050 303040 404030 505020 606010 This means that at Q=10, the suppliers are willing to sell at P=10 and consumers are willing to buy at P=60. Note that the first column is unlabled. Then use Excel's chart wizard...choose line graphs. That should get you a basic supply/demand graph. You can select options to label the axes as P and Q. Hopefully that will get you started.

Question: What power supply does my Acer m5640 need to use a Geforce 9400GT Graphics Card? I dont think the power supply? I dont think the power supply it comes with originally is strong enough. I put the Geforce 9400 gt and everything runs smoothly except the card gets really hot... Thought it would be better to be safe then sorry.

Answer: The card getting hot has nothing to do with the power supply but bad cooling. A Geforce 9400 GT, also known as the 8500 GT, is not a gaming card and doesn't require much power.

Question: What is the difference between supply and quantity supplied? Demand and quantity demanded? My econ teacher says that supply and demand are measures of a person's willingness to buy/sell products, but he says that quantity demanded/supplied is NOT a number. Can anyone clarify the difference for me? Thanks so much!

Question: How to I figure out what power supply will fit my computer? I have a 240 watt power supply in my HP Compaq dc5000 MT computer. I have bought a game card that requires a higher watt power supply. I bought a 500 watt power supply but it didn't fit my computer. How do I get a power supply that is compatible with my computer? I keep going to different sites and none of them tell me anything that clears the question up. I just keep getting more confused. Someone please help.

Answer: Well first off, you can actually measure the outside dimensions of the old PSU and from there, use that as a guideline prior to purchasing a new one. In general most PSU are compatible in all most cases unless the original one is case specific for mini towers, slim cases, or server components. From the little information given sound like your old one was a mini or micro designed for a slim tower or mini desktop case. And if thats the case, you are also limited to the amount of power available to small PSU's. The problem here is the case and not the components, if you like to keep that case, you'll have to find a PSU that can fit in that case. Because you've already purchased the PSU, all you'll need is a new case, then its just a matter of un-assembling the old computer and re-assembling it all in the new case with the new power supply. If you are inexperienced in building computers, you may find a computer store that will do it for you for a fee, or a friend with tech experience. Its pretty easy if you've never done it, its just a matter of screwing things together in a particular order (depends on the case you have). From the link below, its a micro tower, so it probably means its a mATX (mini or micro) sized motherboard as well, so you'd have to find a case that can take mATX sized motherboards.

Question: What is the impact of supply oversaturation in the biodiesel market? Currently production capacity is 580MM gallons; an additional 1,400MM gallons are expected to be produced within the next 18 months, bringing the total supply around 2 billion gallons annually. Demand is very heavy due to government tax incentives and regulations, however at some point the market price of biodiesel has to decrease as consolidation in the supply market (like Exxon) will drive prices lower. Currently price of biodiesel is around $2.75/gallon. What is the impact of supply oversaturation in the biodiesel price?

Answer: Don't worry, the demand for diesel will always be strong, even with stronger conservation measures. The supply, on the other hand, is less assured. Now I'm no economist, and I'm no expert in the oil markets, but I did take econ-101, so I know that fundamentally the price is set by supply and demand. I also know about the theory of "peak oil" which seems real. I believe that "consolidation" could cut costs, and potentially reduce prices. As long as you're not talking about consolidation to the point of a monopoly, then I doubt consolidation will be a primary factor, it's just one of many minor factors. The energy industry is changing year-to-year, but I doubt that it will change drastically overnight in a way that's irrecoverable. Usually a diversity of products and investments brings stability, and less volatility in the market is probably good long-term for consumers, smaller businesses, and green energy.

Question: What is the supply of capital like during a recession? I have to relate the demand and supply of capital to the recession. Is supply of capital (the total savings in the economy) going to be high or low? I already have that demand is going to be low.

Answer: Not necessarily true -- Unfortunately, a lot of people do not realize that an economic recession is actually a fact of life – it may suck – but it is a fact of life. The problem is all you hear on the news media and from politicians is that there is no hope, woe unto us, doom and gloom, etc. There are many benefits during a recession – lots of them in fact. If people just tune out the politicians and the media and focus on what is really going on, everything will get better faster. The outline is simple: Fear causes people NOT to spend. When people DO NOT SPEND, money CANNOT be circulated. When money CANNOT be circulated, the economy cannot grow and is stagnant. When consumer confidence is down and fear remains, nothing gets better, in fact it slows down – hence, a recession. Negativity is what the media and politicians are famous for – after all, it gets ratings and is good for reelections. Good news doesn't “sell” or pull ratings – BAD NEWS DOES! We are being fed the bad, instead of hearing about the good. I'm not that smart, LOL, I learned all of this in The Ultimate Recession Survival Kit, which I highly recommend to EVERYONE. It details all of this, and tells you why recessions are actually good, how to save money and invest it, spending tips, a whole lot more. Excellent resource and helps you see what is REALLY going on. What I learned on it has helped me immensely – financially and emotionally. Don't get caught up in the bull! Get the kit and it'll show you how to turn the recession around to help you, NOT hurt you. There is also a free 5 day ecourse you can sign up for which is extremely encouraging and helpful. I encourage everyone to at least take that. The link to their website is in the resource box. All is not what it appears to be! Hope this answered you ok!

Question: How do Changes in the Money Supply Effect Inflation? I am just a regular person and not an economics student. Regardless, can someone please explain to me (in layman's terms) the effect of changes in money supply on inflation. I understand that demand in excess of supply is a cause of inflation and I've heard that inflation is when too much money chases too few goods (if I remember that line correctly). But what exactly does this mean in layman's terms? How does increasing the money supply effect, for example, the price of a gallon of milk or gasoline? In advance, thank you for any help received.

Answer: The tricky thing with inflation is that there are two different things that are meant when people say "inflation". The first one is the "too much money chasing too few goods" inflation (the cause). Say there is $100 in the economy. If the government increases the money supply to $200, there is suddenly too much money in the economy for the goods there were before. Thus, prices rise as money is now basically worth half as much (it is twice as "easy to get"). The second one is the simple inflation of prices over time (the effect). When the Fed and people on the news talk about the "headline inflation number", etc. they are talking about the percent rise in prices (since some previous date). Since it is much easier to observe inflation through this effect (and not its cause, the money supply), this is what people are usually talking about. (Going a bit deeper here) As the other answerer mentioned, the way this is all controlled is through interest rates. The Federal Reserve is the controller of the U.S. money supply (our central bank), and they watch inflation very closely. They then set an interest rate at which banks can lend from them. This rate then moves through the economy and causes inflation to either slow down or speed up, depending on what they feel the health of the economy is. Hope this helps, and is not too much. Once I get going, I tend to write a lot :) Please feel free to shoot me an email through my profile with any questions... I would be happy to answer them.

Question: How supply and demand plays in the rising of oil price ? Oil price is rising obviously is rising, and it is caused by the demand and supply, with demand exceeds the supply. So, what are actually the factors of these supply and demand... OPEC come into mine as the supplier and China & India's rapid economic growth also come to my mine as the cause of demand. Can anyone explain me more about this supply and demand factors that causes the oil price to increase this much?

Answer: OPEC is a cartel and it operates in ways that milk bad situations. They have no incentive to supply more volumes of crude oil to the market since the obscene amounts of money they now make are way beyond their present and future needs. The oil markets are not "free markets" and you and too many who buy into the classic market model to understand the price behavior, refuse to learn that. People who spoof conspiracy theories need to understand the origin of our anti-trust laws which have been tossed out to favor overconcentration of power in certain commodities particularily in staples that tend to be highly inelastic on the demand side. Google "price fixing behaviors", "Anti-trust behaviors" "OPEC & commodity cartels". If you don't study up on economic history you are welcome to continue believing in the fantasy of "free markets." There are bad people out there with the power to milk us like cows or sheep! As long as you believe in the academic ideal model, you will be victimized over and over again! Now we are looking at a food crisis and price inflation in everything . Do you really think in terms of the classic free market models you learned in school and have been conditioned to trust to explain the economic realities of the real world! I don't anymore!

Question: What power supply would i need for a computer with 2 NVIDIA GeForce 9800 GT 1GB video cards? I am building a computer with the latest techs for gaming. I am planning on Overclocking my processor (an Intel Core i7 w/ 2.66 ghz) and using a liquid cooling system. In addition, I am going with dual video cards and was wondering what power supply would i need?

Answer: Spec wise those GPU's don't appear to need any externel PCIe connectors (so the website says - which surprises me a little, I would have thought they each take a 6 pin power connector). That aside, if you're using a core i7 overclocked, 2 GPUs and therefore a motherboard to accomodate all that plus the usual HDD's and optical drives then I wouldn't go for anything less than 600W. (probably best to get a modular PSU such as: http://www.overclockers.co.uk/showproduct.php?prodid=CA-032-OC&groupid=701&catid=123&subcat= Personally, in a system equipped with those intentions I wouldn't go for 2 9800 GT cards since they are a little dated now. In their place I would recommend 1 http://www.novatech.co.uk/novatech/specpage.html?BFG-GTXP1 or if you're open to ATI, a better card than all of them for this price is http://www.novatech.co.uk/novatech/specpage.html?ASU-4870 Happy building

Question: What power supply unit do you recommend with this computer? I have a Pentium D dual core 3.0 ghz, An XFX 8600 GT 512 mb, 2 hard drives both western digital one is a 80 gb while the other is a 500 gb and running 1.5 gb ram... I currently have a 250 Watt power supply but it keeps getting spiked and burns out after 3/4 months of usage. So what powersupply do you recommand with this computer?

Answer: Let's see what your max theoretical power draw is by heading over to my fave psu calc http://www.extreme.outervision.com/psucalculatorlite.jsp and putting in your components: PD930 (3ghz) / 2 x ddr2 / 2 x hdd / 1 x dvdrw / 4 x fans / 8600gt I get about 242W so you are definitely pushing that unit pretty hard. I would get a unit that can handle at least that much on the +12v combined power such as one of these: FSP Group SAGA+ 400R 400W http://www.newegg.com/Product/Product.aspx?Item=N82E16817104953 $37 w/ free shipping This is a good budget choice, FSP is well known for reliability and can handle +12v@276w combined max http://c1.neweggimages.com/NeweggImage/productimage/17-104-953-18.jpg If you can afford a nicer one this is an excellent choice CORSAIR CMPSU-400CX 400W http://www.newegg.com/Product/Product.aspx?Item=N82E16817139008 $60 w/ $10 MIR & free shipping it can handle +12@30A / 360W http://c1.neweggimages.com/NeweggImage/productimage/17-139-008-08.jpg and corsair needs no defending the quality of it's product. If you didn't know already, the +12v is the most important since both the CPU and GPU get the power from the +12v - your old 250w is probably +12v@14A / 168W max, and your system is currently straining trying to keep up. Putting your total system draw as a guideline for the +12v max is a method that ensures your system will operate within the rated power for the power supply without getting a unit that is overkill, and will last for years to come. If you anticipate any upgrades, plug them into the PSU calc and reevaluate your power requirements then lather, rinse, repeat. Since not all power supplies are created equal, stick with brands (or at least OEM brands) that have a good reputation, and try not to be sold on the total wattage and focus on the +12v power handling. cheers

Question: How can I design a 12V power supply for strobe light with switch? I am trying to design a 12 power supply for a strobe light that will be mounted on my bicycle. If anyone knows how to put a power supply together that will supply at least 100Hrs of power, let me know. I am referring to a small red strobe light. It does not have LED lights on it. OPTX is the brand.

Answer: Are you referring to a bright White strobe light or a Red strobe light? You can use a small sealed lead acid battery feeding a timer circuit that will power LED's which consume very little power.

Question: How does a power supply exactly work? I am planning to buy a 500 watts power supply, but at the same time i want to conserve energy. Does a 500 watts power supplies uses 500 watts every time i run a computer?

Answer: It means that it can distribute a max of 500 watts of DC power to the computer at 1 time. The amount of AC power it's drawing depends on what you're doing at the time, and what your hardware is.

Question: What will happen if i supply a lot of negative ion to engine combustion chamber? Firstly, sorry for my English. I'm a Malaysian and just 15 years old..... What will happen if i supply a lots of negative ion by putting an ionizer to air intake of a car? If i'm right, ignition coil will generate positive ion at spark plug then the positive ion hit the spark plug ground to produce spark. (correct me if i am wrong). If i supply negative ion to the combustion chamber, will it help spark plug to spark better? Any help will be appreciated........... Thanks......

Answer: there are several things for you to understand. 1. spark produced at spark plug in most vehicles are a.c and not d.c current. 2. spark is produced by a very high potential difference of the order of 25000 V even when the current is very less. 3. if you introduce negative ions even with a very large ionizer, most of it will get discharged at the manifold itself as the same is made of metal. further most of the cars have their negative terminal grounded. so you cant introduce a significant amount of ions. in a nutshell, you cannot influence the spark quality with an ionizer. hope this will clear your doubt.

Question: Is it safe to use a 14.5 v power supply instead of the original 16 v power supply on my xbox 360 elite? I have an xbox 360 elite and it came with the original power supply of 16 volts. Then that power supply broke, and I got a newer version of the xbox 360 power supply which is 14.5 volts or 14 volts. Is it safe to keep it running like this?

Answer: NO! WHAT THE FUCK ARE YOU THINKING. You have to use the one that came with your Xbox. It needs 16Volts any thing over or under will fry your Xbox. Only use the 14 Volt as a temporary fix, or you will ruin your xbox. This is not a joke
