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 2002 Mitsubishi Lancer OZ Rally edition. My car is equipped with power locks and keyless entry(unfortunately the previous owner broke the remote and never replaced it). But I got the car used and the power locks have not worked since I bought the car.I have checked the fuse that is supposed to coordinate with the Power door locks(Bank 15, 15A) and it is all good. even replaced it with a brand new one for good measure. I have taken the door panel off and checked the connections to the switch that is in the door and found that there were no loose wires or bad connections.Please help me in knowing what I need to look into next and where I need to go or what I need to do to get my power locks to work again. Thanks so much for your feedback, really appreciate it!!!

First i would recommend getting a Haynes or equal handbook. i purchase them each time i purchase a motor vehicle in order that i do realize the thank you to paintings on them. Locks: with out the handbook for education i would say to start at the fuse and the switches checking for voltage employing a multimeter. From there trace the wiring and be sure for breaks if you havepersistent at the fuse and the change yet they notwithstanding do not paintings that is probably the change. If there is nopersistent at the fuse then trace decrease back from there. From what I even were able of finding there are not any relays for the locks and the locks malfunctioning looks a straight forward subject. homestead windows: In my resources part you will discover a link to a clarification of the position the window relay is placed interior of the fuse field less than the hood. If the relay is robust then i would stick to a matching technique that I defined interior of the part above. Troubleshooting electronics is without doubt one of the greater demanding activities on a motor vehicle reliable success! :)

Q:For our industry due to shortage of power we have provided generator (now running with generator), machines are operating from the generator power. But we have power quality problem there, we have not installed capacitor bank to improve generator power. Do we have any problem if we add capacitor bank panels to improve generator power. Do there any other method to improve power quality. Please note that due to this problem we are facing malfunctioning in our machines.

You need an industrial-sized Uninterruptible Power Supply.

Q:If you have power of attorney over a bank account of a person who has passed away, does that mean the remaining balance is considered your asset and you have the right to that money? Thanks.

NO your power of attorney dies with the person this money is now the responsibility of the state recognized estate executor the POA can go get in trouble if they can't account for every penny after the time of death.

Q:As a beginner in economics im not educated in this field. Why does the gov insure banks? As in what way(s) does it do this and what is it trying to protect or insure by doing so? Dont be afraid to go in detail if necessary as im very interested to hear what you have to say. Thanks yahoo chaters

Simple, so the ordinary people will have confidence in the banking system and deposit money into banks which the banks can then lend out and finance growth.In a nutshell it is simply explained as the FDIC (Federal Deposit Insurance Corp) If you put $4,000.00 in a bank, and the bank becomes insolvent then the FDIC uses it's power to take over the bank. sell off it's investments and reimburse depositors. The FDIC does not reimburse investments, because all investments involve the risk of loss.

Q:and implied powers of the government?thank you.

The expressed powers of Congress are listed in the Constitution. Congress also has implied powers, to make any laws that are necessary and proper to carry out those expressed powers. 1789 The Constitution gives expressed powers to Congress in Article 1, Section 8. 1819 In McCulloch v. Maryland, the Supreme Court holds that the powers to tax, borrow, and regulate commerce give Congress the implied power to establish a national bank.

Q:A power house on a river bank supplies power to a plant on the other side and 5 km. downstream. If the river is 3 km wide and the power line costs Php 4,000 per km. (Php is Philippine peso) on land and Php 5,000 per km. in water. Please show the detailed solution this problem is in differential calculus

A power house B C D plant we shall solve in general form then substitute values let AB w BC x BD wy cost ratio/km water:land k (5/4) angle BAC Θ dist. over water w?secΘ, dist. over land w(y - tanΘ) time C ∞ k?secΘ +(y - tanΘ) dC/dΘ k?secΘ?tanΘ - sec?Θ (ksinΘ - 1) / cos?Θ for minima, sinΘ 1/k which yields x w /√(k? - 1) 3/√((5/4)?-1) 2.25 km ----- you should now be easily able to compute the minimum cost

Q:I am setting up my mobile home with only 12 Volt devices. Could everyone look around their home and let me know what devices they have that are 12 Volt DC powered. As I shop for devices I will only shop from this list.For example, my cell phone is a LG -TMS20, with a LG fast charger model DC-45W which requires 12 Volt input at 0.3A 3.6W.If I use this in my mobile home, I can run it straight off the battery, and I don't need 110Volts AC.I will be making a list of every device you can find which runs off 12 Volts DC. I am looking for computer stuff, and sterio stuff.Thanks for your time

Not so many devices these days actually run directly on 12Vdc - usually they run on 5, 6, 7, 9, etc., Vdc. Rather than restrict yourself to only 12 Volt devices, how about investing in some good quality power Inverters that convert 12Vdc power sources to 110 VAC. Now all those gadgets that use 110 VAC input to convert down to 5, 6, 9, 12, 14, etc Vdc will work off of a single (or multiple) Inverters. Your wind generators, solar panels charge your 12V power bank and your 12Vdc to 110Vac Inverters power everything else in the house.

Q:but JFK passed Executive Order 11110 on June 4th, 1963 that was designed to put new currency, backed by silver, into curculation. Soon after his assassination this money was removed from curculation.How and why does the Fed have so much power? According to the section 8 of the Constitution congress is the only entity that has the right to do this.

You bet it does and it should you too. It was voted in while Congress was in recess over Christmas in 1913 . Check it out on you tube . It's partly the cause of the Great Depression !!!

Q:I tinkered with it and I couldn't get it to turn on a light bulb. My Idea came from youtube I got the exact parts he has the same circuit board the only thing I'm not showing are two switches and my battery i have the switches to keep the current from going to transistor when I turn the thing on, the second is a mystery to me. The circuit board power terminals are on the far left (right:positive) the speaker terminals are on the far right mid board (bottom:positive) He wired the the speaker wires to the PNP transistor and then later added NPN transistor (i was at radio shack and thought about buying a bigger one but the guy said stick with his exact layout until I get the hang of things) I don't know where to put the transistors and have no idea about the switches but I'm assuming one goes from the speakers output to the first transistor

Take the speaker off and connect the contacts to a relay that leads to circuit containing a larger power bank seeing that most kitchen timers now run on one AAA battery. Then to clips for your e - match . Note with this design the timer signal will pulsate the relay for a single on switch it is required to connect the secondary coil contacts to the primary so the circuit keeps its self closed then after launch the circuit will open by itself
