The AF120 says it will handle up to 15 amps.

The "power consumption" spec for my Samsung HDTV only says "200 watts". I have a bunch of other stereo/electonics stuff I want to run through the AF120, but I don't want to overload it. As long as the circuit breaker doesn't pop now, the AF120 will probably handle everything I want.

But, out of curiosity, is there a way to convert watts to amps?

It's not exact, but a quick and easy way is to take the amps times 100. It's more exact to take it times 117v., but the 100 gives you a quick mental picture. Doing this, 15 amps means you can draw up to 1500 watts with just a little saftey margin built in (about 200 watts). It's always a good idea to leave some saftey margin in figuring loads.

Real men us real math. :-) E=volts, I=amps, R=ohms, P=watts

Ohm's Law says that 1 volt will push 1 amp through 1 ohm, or another way, 1 volt is required to push 1 amp through 1 ohm.

E=IxR, I=E/R, R=E/I

If you increase the voltage or decrease the resistance, the current increases, and vice versa.

Watt's Law says that 1 amp at 1 volt produces 1 watt, or another way, 1 watt is dissipated by 1 amp pushed by 1 volt.

P=ExI, E=P/I, I=P/E

If you increase the voltage or increase the current, the power increases.

To use any of the above formulae, place the unknown value to the left.

Now, back to the original question. The formula to convert amps to watts is to multiply amps by 120. P=ExI= 120 x 15 = 1800 watts.

OK, I divided 200 watts by 116.9, my current (no pun intended) line voltage, and got 1.7108639.

Thanks, guys!

As for the rest of the thread, I'll let you guys fight it out! hahaha
