To start a car engine, the car battery moves 1.27 ✕ 1021 electrons through the starter motor. how many coulombs of charge were moved?

To calculate the amount of charge in coulombs moved by the car battery, we use the formula

Here, N is the number of electron and   is the charge of electron.

Given and we know

Substituting these values in above formula we get,

Solution:

According to the question we have to use the formula Q=ne

Since we have given

q=1.6*10^(-19) and the car moves the electrons is 1.27*10^21

thus for calculation

1.27*10^21*1.610^(-19)

 =2.03*10^3C

 =203C
