Physics Class 12
Solutions to CBSE Sample Paper - Physics Class 12

An ac voltage V = V 0 sin ωt is applied across a pure inductor of inductance L. Find an expression for the current i, flowing in the circuit and show mathematically that the current flowing through it lags behind the applied voltage by a phase angle of  λ/2. Also draw graphs of V and i versus ωt for the circuit.
