Question

In series LCR circuit, the phase difference between applied voltage and current is 

a) positive when \( X_{L}>X_{C} \)

b) positive when \( X_{C}>X_{L} \)

c) \( 90^{\circ} \)

d) \( 0^{\circ} \)

Answer 1

The correct option is a) positive when X_L > X_C 

Let the phase difference between applied voltage and current in series LCR circuit be ϕ.

Thus, it is positive for X_L > X_C.
