Phase Angle in LCR SeriesHardQuestion 20208

Question

In a series LCR circuit with X_L > X_C, the current:
  1. A
    Leads voltage by φ = tan⁻¹[(X_L−X_C)/R]
  2. B
    Lags voltage by φ = tan⁻¹[(X_L−X_C)/R]
    Correct
  3. C
    Is in phase with voltage
  4. D
    Leads by 90°

Correct answer

Lags voltage by φ = tan⁻¹[(X_L−X_C)/R]

Explanation

When X_L > X_C, the circuit is inductive — current lags voltage by φ = tan⁻¹[(X_L−X_C)/R].
