State the principle of conservation of electric charge

Explanation

Conservation of charge: The law of conservation of charge states that the total charge (algebraic sum of positive and negative charges) in an isolated system remains constant.
The electric charge can neither be produced nor destroyed. This law has been found to be true for all events as well as for those at nuclear and atomic levels. in other words, there is no exception to the law. like the law of conservation of energy, the law of conservation of charge is also a universal law.
Examples. (i) When a glass rod is rubbed with silk, the charges developed on the glass rod and the piece of silk are equal and opposite.
(ii) Charge is conserved in all chemical and nuclear reactions.
