Meaning
The law of conservation of charge states that charge cannot be created or destroyed, it can only be transferred from one particle to another.
About Conservation of Charge
- The overall charge of the Universe is zero.
- If a charged particle comes into existence another particle with opposite charge must also come into existence.
- Conservation of charge can be applied to all fundamental interactions to balance the equations and to ascertain the types of particles produced.
