Question #7800

How much charge passes through a starting motor, if it takes 4.0 s to start a car and there is a current of 255 A during that time?

Expert's answer

The coulomb is defined as the charge transported by a steady current of one ampere in one second. So,

Q = I·A = 4·255& = 1020 C.

Q = I·A = 4·255& = 1020 C.
