An LCR series circuit is connected to an oscillator (AC supply) having RMS voltage 200 V . If the RMS voltages across resistor, inductor and capacitor are equal, then RMS voltage across the resistor would be

Options

  1. A100 V
  2. B200 V 2
  3. C200 V
  4. D100 2 V

Correct answer

C. 200 V

Step-by-step solution

∵ V = V R 2 + V L - V C 2 = V R ∵ V L = V C V R = V = 200 v o l t
