Question

Calculate the number of electrons constituting one coulomb of charge class 10 cbse

Answer 1

Charging on the electron is negative and therefore -1.6⨯10-19 is coulomb, therefore 1C charge 1 / (-1.6⨯10-19) = 6.25 ⨯ is done by 1018 electrons. So if 1 flow flows through a conductor, then it implies

6.25 ⨯ 1018 passes one second per second in the cross section of the electron conductor.

Answer 2

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
