If charge is destroyed, it is a violation of the law of conservation of

This is a violation of the law of conservation of charge.
This law states that the total charge in a given system must remain constant, and charge can neither be created nor destroyed. In calculating the net charge present; however, the signs of the charge (positive and negative) are accounted for. Proof for this law was provided by Micheal Faraday in 1843.
