Properties of electric charges:

(a). Electric charge is an intrinsic characteristic of the fundamental particles making up those objects.

(b). There are two kinds of electric charge: positive charge & negative charge.

A glass rod is rubbed with silk, the electric charge on the glass rod is called positive charge.

When rubber is rubbed with fur, the electric charge on the rubber is called negative charge.

(c) . The object contains equal amounts of two kinds of charge, the object is said to be electrically neutral.

If two types charge are not in balance, there is a net charge, we say that an object is charged.

(d). Like charges repel one another and unlike charges attract one another.

(e). Objects become charged by gaining or losing electrons.

Because electrons are transferred from one object to the other, one object gains some negative charge

from the electrons transferred to it while the other loses an equal amount of negative charge and is left with a positive charge.

(f). The net charge in an isolated system is always conserved.
