Production of Charges

Electric charge is conserved in an isolated system, in any chemical or nuclear reaction, the net electric charge is constant. The algebraic sum of the fundamental charges remains the same.

The unit of electric charge in the meter-kilogram-second and SI systems is the coulomb, equivalent to the net amount of electric charge that flows through a cross-section of a conductor in an electric circuit during each second when the current has a value of one ampere. One coulomb…
