According to the principle of conservation of charge the total electric charge in an isolated system never changes. The charges are neither created nor destroyed; they are only transferred from one body to the other.
A charge is a property associated with the matter due to which it produces and experiences electrical and magnetic effects. Conservation of Charge is the principle that the total electric charge in an isolated system never changes. The net quantity of electric charge, the amount of positive charge minus the amount of negative charge in the universe, is always conserved.
Examples of conservation of charge:
- The net charge will be zero when two bodies are rubbed against each other where there is an exchange of charges.
- There is zero net charge production when a radioactive decay of proton takes place resulting into a positron and neutron.
