The electric charge may be defined as that property of matter due to which the matter is able to exhibit electric , magnetic ,and electromagnetic effects .
A basic property of some elementary particle of matter by virtue of which they develop electrical influence is called electric charge .
A charge can be positive or negative . Electric charge can not exist on its own , it always requires a mass to sit on . But electric monopole is possible i.e. positive and negative charge can exist independently e.g. an electron carries only negative charge on it .
Like charge repel each other whereas unlike charges attract each other .
Rubbing a glass rod with silk gives positive charge on the rod .
