Question

determine the number of electrons required for one coulomb of charge

Answer 1

Q = n×e
Q=1
e= 1.6 × 10^-19
n= Q/e
=(1×10^-19)/1.6
=(10^20)/16
= (100/16)×10^18
=6.25×10^18 or 6×10^18 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
