The starter motor of a car engine draws an electric current of 20.0 A from the battery. The copper wire to the motor is 5.90 mm in diameter and 1.57 m long. The starter motor runs for 0.65 s before the car engine starts up. How much electric charge passes through the starter motor

q = 13 C

Explanation:

Given that,

Electric current, I = 20 A

The starter motor runs for 0.65 s before the car engine starts up.

We need to find how much of electric charge passes through the starter motor. Let it is q.

Electric current = electric charge/time

So, 13 C of electric charge passes through the starter motor.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
