Question

calculate the number of electrons constituting one coulomb of charge ​

Answer 1

Here is your answer

we know that the charge of electron is 1.6 × 10^-19 coulomb.

Of charge is 1C, no of electron = 1/1.6 × 10^-19 × 1

= 10^19/1.6

=10/1.6 × 10^18

=6.25 × 10^18

This, 6.25 × 10^18 electron taken together constitute 1 coulomb of charge.

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
