## Electric Charge – Definition

Charge is an Intrinsic property of matter. The SI unit of electric charge is coulomb. The symbol of charge is Q. There are two types of charges Positive (+ve) and negative (-ve). Sames charges repel each other and opposite charges attract each others. Charge can neither be created and nor be destroyed.
