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


Theres always enough room in the junction box.You just need a bigger hammer

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.)
