ECN Forum Forums General Topics of the Trade General Discussion Area Volts and amps?

I know volts/watts = Amps but how do I figure out the watts from and amp reading? A fan (12V DC Computer fan) says 0.25A how so I figure out watts? thanks

It's actually Watts/Volts=Amps.

You can rearrange the formula to Watts = Volts x Amps, so for your fan 12V x 0.25A = 3W.

(That's for DC; it can get more complex for AC.)

Wizkid, if you are the specialist that your name suggests, this is Basic Ohms Law + Transposition of an Equation, easy!.
I can work these things out in my head!.

Er, there's this.
