Question

if charge of an electron be 1.6×10^-19C,how many electrons should pass through a conductor in 1sec to constitute 1amp.current​

Answer 1

Answer:

Given that

Charge (Q) = 1 C

Electron (e) = 1.6× 10^-19

Number of electron (n) = ?

Q= ne

1 C = n × 1.6×10^-19 C

n = 1/(1.6×10^-19)

n = 6.25 × 10^18 electron.
