Question

Find the number oc electrons that constitute 1c of charge

Answer 1

The charge on an electron is negative and it is -1.6, 10-19 coulomb therefore, 1 C charge is carried by 1/ (-1.6⨯10-19) = 6.25  , 1018 electrons.

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
