Question

a current of 5 Amperes flows through the conductor. The number of
electrons per second will be
a. 1.6 x 10-19
b. 3.12 x 1019
c. 4 x 1019
d. 7.68 x 1020

Answer 1

Answer:

(b) 3.12 X (10^19)

Explanation:

i (current) = n q(charge over electron) / t (time)

t=1 sec

q= 1.6 x 10^-19 C

i= 5 A

n=5 X 1 /  1.6 x 10^-19 =  3.12 x 10^19

Hope this helps
