The SI unit of electric field is the volt per meter (V/m). Electric charge is the fundamental physical property of matter because of which the matter experiences a force whenever it is kept in an electromagnetic field. The process of charging an uncharged conductor by bringing it near a charged conductor without any physical contact is known as charging by induction. Coloumb is the unit of electric charge. One coulomb is the quantity of charge transferred in one second. Mathematically, the definition of a coloumb is represented as: Q = I.t In the equation, Q is the electric charge, I is the electric current and t is the time.
