Conservation of electric charge i. The total electric charge of the universe is constant, no physical process can increase of decrease in the total amount of the electric charge in the universe; electric charge can only be transferred c. Polarization i. The ability of charged objects to attract small neutral objects 1. When a positively charged object is held near a neutral object the opposite charges are attract
