Question

A 12 v automobile battery is connected to an electric starter motor. the current through the motor is 246

a. how much power does the motor dissipate? answer in units of w.

Answer 1

The power dissipated by the motor is given by:
$P=VI$
where V is the voltage of the battery and I is the current flowing in the circuit.

In our problem, the voltage is V=12 V and the current is I=246 A, so we can calculate the power dissipated by the motor using the previous equation:
$P=(12 V)(246 A)=2952 W$
