RL and RC Series Circuits

In an a.c. circuit, a resistance R is connected in series with an inductance 'L'. If phase angle between voltage and current is 45∘45^\circ, the value of inductive reactance will be

(sin⁡45∘=12=cos⁡45∘\sin 45^\circ = \frac{1}{\sqrt{2}} = \cos 45^\circ)

Show answer and solution

Answer: (b)

  1. For series RL: tan⁡ϕ=XLR\tan\phi = \frac{X_L}{R}.
  2. tan⁡45∘=1⇒XL=R\tan 45^\circ = 1 \Rightarrow X_L = R
  3. So the answer is (b) RR.
