The starter motor of a car engine draws a current of 170 a from the battery. the copper wire to the motor is 4.60 mm in diameter and 1.2 m long. the starter motor runs for 0.930 s until the car engine starts how much charge passes through the starter motor?

The charge that passes through the starter motor is .

Explanation:

Known Data

First Step: Find the number of the electrons per unit of volume in the wire

We use the formula .

Second Step: Find the drag velocity

We can use the following formula

Finally, we use the formula .
