How do I go about converting 125 VAC to Volts or Amps?

I found this equation.. VOLT-AMPS= 1.732 x VOLTS x AMPS

But I'm not sure if it's the correct equation. Can someone confirm this?

125VAC = 125 Volts Alternating Current

You can't change Volts into anything else but volts.

amps- Columbs/sec
Volts- Joules/Columb
They are units for different things. 1 Amp is a measures the flow of current while 1 volt is a measure of the electrical potential. Dimensional Analysis is your friend.

Edit: what do you need to do anyway.

and besides...you should really be looking for either electricians or electrical engineers....not physics ppl hehe, although i'm sure many physics people know about this stuff too.

what are you doing exactly? 125VAC to Volts? Is this a transformer question? There is ohms law, where you can relate V(Voltage) to I(current) and R(resistance).

Actually, there is Volts RMS, Volts Peak to Peak, Peak Voltage, average Voltage etc.

Also, for radio transmission, the output voltage can be converted to %Modulation, dBm, or even duty cycle.

125VAC is assumed to be VRMS.

yeah...if we really want to scare him, we could bring up power factors and converting watts to volt-amps :)

I took this stuff in Physics 2 last term for my chemistry degree... It's fairly straightforward stuff.

AC consists of Volts, amps and ohms. You must have two to get the third one.

Volts = Amps X Ohms

Amps = Volts/Ohms

Ohms = Volts/Amps

No sir. It is the amps that kill. A minimum of .2 milliamps is all it takes to kill. I just took the NATE certification test for HeatPumps on Monday and that was one of the answers to one of the questions.

true only in a purely resistive circuit.
