The phase diffenernce between the alternating current and emf is `(pi)/(2)`. Which of the following cannot be the constiuent of the circuit?

A

L alone

B

LC

C

R,L

D

C alone

Text Solution

Verified by Experts

The correct Answer is:
C
L,C or LC can produce a phase difference of `(pi)/(2)` between alternating current and e.m.f. but it R is present, then the phases difference will lie between 0 and `(pi)/(2)` but it will not be `(pi)/2`.
