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

a) π/4
(b) π/2
(c) zero
(d) π/6
​

Answer 1

Answer:

fhghvh sorry it went by mistake

Answer 2

ϕ=tan−1(RXL)

=tan−1(33)

=tan−1(1)

=4πrad
