Q:12V Battery Bank Question?
To pull 200 W from a 12 V batttery for 12 h PU * I (Ohm's law) It will draw at the rate of 16 2/3 A Therefore you need to have a battery of 12 * 16.6666 * 12 2 400 Wh total capacity. Read the label on your battery. If it is a bank of several batteries, then the capacity it's the sum of all. Now, you should worry about how deep you are discharging your battery. A NiCad cell can go practically to zero and happily recharge again. Don't let it go absolutely flat, then it may re-charge with opposite polarity. (!) A Lead Acid cell (and most automotive types) will not recharge well if you discharge them more than about 40 % (of total rated capacity) - Yes, that is true, automotive batteries are not made to be discharged often. NiFe (Nickel-Ferrite) cells are very safe for repeated discharges too. (Mr. Thomas Alva Edison's contribution to the world) Most other cells in use today can be deep-discharged without ill effects.
Q:If you own or control all the central banks do you control the world?
I'm not sure I understand the question. Governments DO control all the central banks in the world.
Q:is jd power a legit source for bank ratings? are they paid off? trying to decide on wachovia or commerce bank?
JD Powers is an independent research company a division of McGraw- Hill.
Q:Can someone help me help someone with bank and internet fraud.?
felony fraud. exciting term. An oxymoron. yet, confident, I do agree that this is felony fraud, in that the *banks* are those that are incomes pastime on that our online worldwide funds collectively as this is pending pass from one financial company account to the different. this is reminiscent of a few of the banking rules here interior the united states. particular sorts of gadgets for deposits could be held with the help of the financial company for 7 days till now a withdrawal could be made against the money. The banks frequently state that the clarification is to insure that the tool clears, i.e. that there are sufficient funds interior the originating account. besides the undeniable fact that, the financial company is somewhat incomes pastime on your funds collectively as you won't be able to apply it.
Q:Among the Four Tigers, which has emerged as the largest industrial power?
This is just a guess but it's pretty close between A and B
Q:Have a ?are banks system worth while. will it give me horse power to get over mountains, wood also give me a ?
YES it will give you more power for pulling hills you should get this done sooner not later and give yourself time to work out any bugs in the system. Find someone who has a lot of knowledge doing this so that it gets done right the first time. You may need to upgrade the exhaust to make extra power you are going to lose a couple miles per gallon but it will be well worth it in the end.
Q:How to charge a flash capacitor bank?
A DC power supply that can deliver about 290 volts (NOT over 300 volts) will do that. A series power resistor based on the current output of the supply will limit the peak charging current to a safe value. For example, a voltage doubler from the 120 VAC line will deliver 330 volts DC. If you can find a transformer with a 200 volt 1 amp secondary, that will produce about 280 VDC. A 100 ohm power resistor in series will limit the current to 3 amps. Peak power in the resistor would be 1000 watts. Resistors in this capacity are very expensive. I'd try 3 120 volt 200 watt light bulbs in series instead. Under that setup, charge time will be: time constant is 100x10x0.16 160 seconds, and several time constants will get you charged up. EDIT, I'm taking your word on the caps size, and the above calculations reflect that. But I think they are actually 160µF, not 160mF. The latter would be much too large to fit in a cameral. Capacitor manufacturers tend to use m when they mean µ for some reason lost in history. In that case, the series resistor need only be a 500 ohm 50 watt unit and the charge time will be a few seconds. .
Q:Which Bank is better Wachovia or Chase?
Use a bank that is prominent in the area you go to school. If one bank has no ATM's or branches what good is it to you, so go with a bank that has a large prescence in the community that your in.
Q:Looking for 12 Volt technology devices for mobile home?
I think you're gonna like this Two types of places where I have found an abundance of 12V appliances and devices: (1) Sporting GoodsCamping store; like Cabela's or Bass Pro Shops (2) Truck Stops. Truckers need devices that work on their truck batteries. It's amazing what you can find. And as one other person commented, you can easily find 12VDC to 120VAC inverters for small (under 200W) appliances. The two places mentioned above, as well as any decent department store or auto parts store, carries these inverters. Just be sure the appliance you plug into one is power rated at less than 75% of the inverter's power rating.
Q:98 deville power problem?
with out checking the motor vehicle for loose front end aspects, it may well be perplexing to assert what the probelm may well be. it must be someting approximately waiting to permit loose on you nevertheless, to the place you will possibly lose your guidance thoroughly, so it needs to be looked at ASAP. there may well be a ball joint, tie rod end, or different front end area that's bent or failing, and extremely practically waiting to permit loose thoroughly it could additionally be the means guidance rack itself that is going undesirable, or a tire loose (lugs loose) or a substantial subject with the wheel alignment or balancing of one or the two between the front tires. despite if it isn't the tires themselves being loose, that's uncertain, then i might lean in direction of something having way too plenty play interior the front end, from placed on. a different choose for instant prognosis!
