State the principle of conservation of charge​

The principle of conservation of charge states that the net charge of an isolated system remains constant during any physical process.

The quantization of electric charge is the property due to which all free charges are integral multiple of basic unit of charge of an electron (or proton) represented by e. The basic cause of quantization is that only integral no. of electrons can be transferred form one body to another on rubbing.

Hope it helps!!!
