Explanation / Answer

Gievn that,

I = 24 A

We know that, by the defination of current, Current = charge / time

I = n x Q / t , where n is the number of electrons. and t is the time and t = 1 s and Q = e = 1.6 x 10-19 C

n/t = I / Q = 24 / 1.6 x 10-19 = 15 x 1019 electrons/sec

Hence, n =  1.50 x 1020 electrons/sec

In one minute, No of electrons will be:

N = 1.5 x 1020 x 60 = 9.00 x 1021 electrons per minute.

Hence, N = 9 x 1021 electrons/minute.
