What is the formula for determining the watts produced by the alternator?

In general, Ohms Law says that watts equal the product of voltage times current. But if you have a 12 V generator with a 120 ohm load across it, there will only be about .1 A flowing through the resistor, not 35 A. The current rating merely tells you how much current can be safely passed through an external circuit without damaging the generator. In this case, a load resistance of 12/35 ohms (about .343 ohms) would consume 35 A and require the generator to provide 35*12=420 watts (or 420 Joules/second) of energy.

watts=volts x amps, so it's 12 x 35=420 watts.

Formula:...Watts = Volts x Amps.

Watts(P) = Volts(V) x Amps(I).
P = 12 x 35
P = 420 watts.
Your current rating is very high.

v*I. where V is the Potential diff betwen the terminals of the battery and I is the current passing thr the the circuit .....other formulaes are I*I*R

all you have to do is 1-2 step 1-2step and just keep on going
