Question

how many electrons passing pee second in a circuit iin which there is 15 ampere current​

Answer 1

Current i : 15 A

Time t : 1 second

Charge e : 1.6 x 10^(-19)

Q = it

ne = it

n = it/e

n = 15 x 1 / 1.6 x 10^(-19)

n = 9.375 x 10^(-19)

n = 9375 x 10^(16)

Thankyou, Hope it answered your doubt
