An alternating emf is applied across a parallel combination of a resistance R, capacitance C and an inductance L. If `underset(R )(I)`, `underset(L)(I)` and `underset(C )(I)` are the currents through R,L and C respectively, the phase relationship among `underset(R )(I)`, underset(L)(I)` and `underset(C )(I)` and source emf E, is given by

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Current in inductance `underset(L)(I)` lags behind , cuurent in resistance `underset(g)(I)` is in phase with voltage , while current in capacitance `undetset(C )(I)` leads by a phase of `pi`/2
