Q:if so how is it done?
You do realize, that trust is involved, right? Even though your contract/poa states they can only spend the money on your behalf, no one is going to enforce that. If they steal from you, there is basically no way to get the money back.
Q:I have a bank of 10 flash caps all rated at around 300v and about 160 mF apiece. How do I charge this?
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 160?F, not 160mF. The latter would be much too large to fit in a cameral. Capacitor manufacturers tend to use m when they mean ? 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:I have a small battery bank used in my solar powered workshop anyway back to the question.I wanted to run some garden light from my power inverter about 200watts of lights what battery capacity would i need to run that for lets say 12hours
200 watts 120 volts x ? amps The current is 1.7 amps. ? amphours 1.7 x 120 The amphour capacity if the battery needs to be at least 200. That would only be true if the inverter was 100% efficient. They all produce heat and consume some energy. I'll speculate an 80% efficiency, requiring a 25% adjustment to 250 amphours. Unless you've an impressive array, you are likely asking too much of the solar panels.
Q:A. It would cause problems with France. B. It gave the government too much power. C. It would be good for farmers and bad for merchants. D. It would hurt the nation's economy.
B. The Anti-Federalists (Jefferson among them) wanted a weak federal government and strong state's rights, a national bank gave the federal government too much power in their eyes.
Q:Bank of America Online Investing Powered by Merril Lynch
Bank of America? Didn't the government bail them out? Read the fine print carefully, the Feds are running that bank. Grandpa
Q:I got a '05 Duramax and want some more power. Is anyone better than the other for Chevy? Anything I should know before?
i'd say edgemy friend's brother has one and he's gettin' over a thousand foot/lbs of torque and over 600 horsepower i think.
Q:I have a four 6 volts deep cycle battery bank arranged to output 12 volts powering a 12 volt power inverter. The inverter has its own built-in charger as the electricity comes and goes where I live. So far so good. In case there is a power failure for, say, two days. Can I use my car to charge the battery bank? I'm thinking about using jump cables. How long will it take for the alternator to fully charge the four batteries?
It will work, after a fashion, but: You won't get much charging out of that alternator at idle. (You'll want that engine at about 1200 RPM minimum.) You will be draining the car battery initially. (This might be a serious drain if the battery bank is large in comparison to the car battery.) If the battery bank is much larger than the car battery, you might be overloading the alternator when you first start recharging. Don't let it heat up too much.
Q:i live in UK and want to know what degree to do, I have applied for International business , business economics in liverpool. Banking and Finance in Bangor University. business studies, business and economics in Manchster. which coarse would be the best . thanks alot to anyone who gives a decent reply :)
Understand that the prestige of your university and your GPA count more than the major you choose. People often push quantitative majors but they're certainly not the only ones getting ibanking jobs. A non-quantitative major can easily alleviate fears of inadequacy by taking a few math courses (calc 1, 2, 3, diff eq, linear algebra, etc). Any of the degrees you listed could get you into ibanking -- chose the one that interests you most so that you can get the highest GPA possible. Internships would be quite useful, but they tend to be a hit-or-miss thing depending on your location.
Q:A.allowing South Carolina to secede from UnionB.depositing federal funds in the National BankC.refusing to be bound by Supreme Court decisionsD.vetoing the Force Act of 1833 Some people said it's C.But in my textbook, the author uses lots of paragraphs to talk about the veto rights to thge congress to gain more presidential power.So, I became confused~
The answer is C. Jackson was against nullificatiion by S. Carolina. Jackson was against Nicholas Biddle and the National Bank of the US but believed ina stronger bank system of individual states. He was for the tariffs in South Carolina that were part of the Force Acts of 1833. Jackson was once quoted as saying The Court has made their ruling , now let them try to enforce it.
