defence exam Agniveer Vayu Group X & XY Mock Test 01/2026 Physics Electromagnetic Oscillations and Alternating Current
An alternating e.m.f. is applied to a purely inductive circuit. The phase relation between e.m.f. and a current flowing in the circuit is
1
e.m.f. is ahead of current by π/2
2
Current is ahead of e.m.f. by π/2
3
Current lags behind e.m.f. by π
4
e.m.f is lags of e.m.f. by π
