Series LCR Circuit

In an LCR series circuit, the potential difference across the terminals of the inductor, capacitor and resistor is 60 V, 30 V and 40 V respectively. Then supply voltage will be equal to

Show answer and solution

Answer: (b)

  1. V=VR2+(VL−VC)2V = \sqrt{V_R^2 + (V_L - V_C)^2}
  2. V=402+(60−30)2=1600+900=50V = \sqrt{40^2 + (60 - 30)^2} = \sqrt{1600 + 900} = 50 V
  3. So the answer is (b) 50 V.
