Ampere Maxwell Law & Displacement Current
Gauss’s law and Faraday’s law for magnetism. Ampere – Maxwell law shows that the total current passing through any surface of which the closed loop is the perimeter is the sum of the, conduction current and the displacement current. Displacement current produced due to change of electric field or electric flux with time during the procedure of charging or discharging of capacitor. See Answers.
