Two electric charges attract or repel each other. Therefore, some work has to be done in moving the charges away from each other, or in bringing them closer to each…
Gauss Law : The electric flux ΦE passing through a bonded surface is 1 / Ɛ0 times the total charge q enclosed by that surface. Before we discuss about gauss…
An electric cell is a device that converts chemical energy into electrical energy and maintains a constant flow of charge in a circuit. It consists of two rods of different…
