Question

What is the number of electron that constitutes a current of one ampere 1) 6.25 × 10–18 s–1 2) 6.25 × 1018 s –1 3) 8.22 × 10–12 s–1 4) 8.12 × 1022 s –1

Answer 1

Answer:2) 6.25×10^18

Explanation:q=ne

Let q=1C,

e=1.6×10^-19(this is charge of one electron)

n=q/e

n=1/1.6×10^-19

n=6.25×10^18electrons
