Question

An ac voltage is applied to a resistance R and an inductor L in series. If R and the inductive reactance are both equal to 3 Ω the phase difference between the applied voltage and the current in the circuit is

(a) π/6

(b) π/4

(c) π/2

(d) zero

Answer 1

Correct option  (b) π/4

Explanation:

Here, R =3 Ω

Inductive reactance, X_L =3 Ω

The phase difference between the applied voltage and the current in the circuit is
