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

Options

A.
B.
C.
D.

Answer

C

Explanation

In inductive circuit, current lags behind voltage by an angle of `pi // 2`
In capacitance circuit, current leads voltage by an angle of `(pi)/(2)`
