Calculate the number of electrons constituting one coulomb of charge.

Asked by Vishal kumar | 1 year ago |  229

##### Solution :-

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

According to charge quantization,

Q = nqe, where n is the number of electrons and qe 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:

$$1 C = n\,\times \,1.6\, \times10^{-19}$$

$$n= \frac{1}{1.6\times10^{-19}}= 6.25\times10^{18}$$

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