Question 3

Calculate the number of electrons constituting one coulomb of charge.

Answer

Charge is flow of number of electrons.

Q=ne

Q is charge, n = number, e = electron

Whereas, One electron possesses a charge of 1.6 × 10⁻¹⁹ C,

i.e., 1.6 × 10⁻¹⁹ C of charge is contained in 1 electron.

∴ 1 C of charge is contained in

Hence, 6x10¹⁸ electrons constitute one coulomb of charge.
