Electric charge It is defined as the fundamental quantity of electricity. Or, It is referred as a particle which experience force when placed in an electric field or when it is moving in a magnetic field. The SI unit of electric charge is coulomb 'C'. Its dimension is 'AT'. It is of two types: Note: In reality, the charge of a down quark is '-e/3' and charge of an upquark is '+2e/3', but they always found in collection and not in singular form. Properties of electric charge 1. Additivity of charge The net charge of any system is the algebraic sum of all the charges present in the system. For example, a body contains charges as shown in figure... 2. Conservation of charge The total charge of any isolated system remains conserved i.e., it can neither be created nor be destroyed but it can only be transferred from one place to another inside the system. For example, when you rub a plasti
