An inductor of inductance and resistors of resistances are connected to a battery of emf 12 V as shown in the figure. The internal resistance of the battery is negligible. The switch is closed at . The potential drop across as a function of time is
As we learnt in
Self Inductance -
An emf is induced in the coil or the circuit which oppose the change that causes it. Which is also known back emf.
