An ac voltage is applied to a resistance R and an inductor L in series

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 3Ω, the phase difference between the applied voltage and the current in the circuit is

Options

(a) π/6
(b) π/4
(c) π/2
(d) zero

Correct Answer:

π/4

Explanation:

The phase difference is given by
tan ? = Xₗ / R = 3/3 = 1
? = π/4
