Calculate the number of electrons constituting one coulomb of charge.

Solution:

The value of the charge of an electron is 1.6 × 10^-19 C.

According to charge quantization,

Q = nq_e, where n is the number of electrons and q_e is the charge of an electron.

Substituting the values in the above equation, the number of electrons in a coulomb of charge can be calculated as follows:

Therefore, the number of electrons constituting one coulomb of charge is 6. 25 × 10¹⁸.
