Question

How many electrons flow per second in a circuit when 0.5 amphere current flows through it?

Answer 1

Hey Mate

your answer is ---

Given, current l = 0.5ampere ,
time t = 1sec

we know that

l = Q/t

=> Q = 0.5×1

=> Q = 0.5coulomb

now,

Q = ne

=> n = Q/e

=> n = 0.5/1.6×10^-19

=> n = 3.1 × 10^18

hence, 3.1 × 10^18 electron flow per second in a circuit when 0.5 ampere current flows through it
