capacitors

Can someone explain a capacitor and it's uses. Tying in audio systems and LED and neon lighting.

paralel in less than 4 sec? i'm running 2- 2000 joule capacitors in paralell and need them to discharge 340 dc current in less than 4 seconds

i got a deck then it touched some metal and now the speaker wires don't work so i wanna know what the ohms are for resistors or capacitors some are 10-15v but i don't know how much ohms they are or how to check to see if there good i was thinking maybe hooking it up too a 12v battery and seeing...

I have a 220Amp H.O. Alternator, a 1900 Shuriken Powercell in the front and a 2400 Powercell in the back. System RMS is 3600-RMS at 2ohms Bridged at 14.4 volts The Batteries are separated by a 200-AMP battery Isolator.The rear battery sits at 13.01 volts, just sitting, no draw or charge. The...

a capacitor is like a small battery so really nothing just fuse it right and you will be good you have enough battery and alternator for your system

Don't waste your money on a capacitor. They are worthless. A 220A alternator should be plenty for your batteries and system. I suspect that the rear battery does not have a good enough ground. This could be because the grounding point of the battery has too much resistance (compared to the...

my 32 inch samsung t.v. burned out and i checked it in the back, 3 capacitors were burned out. How much will it cost to replace this.

How long do these last? What if I wanted to buy an unopened capacitor that is from the early 2000's? Is it a bad idea? I really like the look of it, that's why.

Also, what are the "pros" and "cons" of this?

the noise in telephone line? how to decrease the telephone line noise by attaching capacitors or diodes. i attached a diode and the phone line worked and then i attached it in reverse then the line did not work. then i attached a capacitor the line worked. this mean that the line is AC. my my...

When you can use a capacitor to filter/smooth a rectified signal in a power supply.

How do you find the capacitance of a capacitor bank? Also, is there a specific direction you need to put resistors or does it matter? Thanks in advance.
