Name two basic properties of electric charge.

There are very two basic properties of electric charge. They are: 1. Conservative nature of charge Electric charge of a particle is conservative in nature. It means that the charge can neither be created nor be destroyed 2. Quantization of charge The charge of a system is a fixed quantity. Technically, the charge is a quantized quantity. The net charge of a system can be expressed as the integral multiples of the basic unit of charge
