ELECTRIC CHARGE
According to Sir William Gilbert, electric charge is defined as the property of material objects due to
which they exert electric force on one another.
TYPES OF ELECTRIC CHARGE
1. Positive charge: The substances which looses the electrons acquire positive charge.
2. Negative charge: The substances which gains the electrons acquire negative charge.
UNITS OF CHARGE
(i) The S.I. unit of charge is coulomb.
(ii) The C.G.S electrostatic unit of charge is stat-coulomb or esu.
CONSERVATION OF ELECTRIC CHARGE
STATEMENT
In an isolated system, the total charge always remains constant
OR
In an isolated system, charge can neither be produced nor destroyed but it can be transferred from one
part of the system to another part
Quantization of electric charge:
According to charge quantization, any charged particle can have a charge equal to some integral number
of e, i.e.,Q =ne where n=1, 2, 3,….Here, e is the value of charge on the electron.
