Series LCR Circuit

In an LCRLCR circuit, if ' VV ' is the effective value of the applied voltage, VRV_R is the voltage across ' RR ', ' VLV_L ' and ' VCV_C ' is the effective voltage across ' L ' and ' CC ' respectively then

Show answer and solution

Answer: (c)

  1. VRV_R is in phase with current; VLV_L leads by 90∘90^\circ and VCV_C lags by 90∘90^\circ, so they subtract.
  2. Phasor sum: V2=VR2+(VL−VC)2V^2 = V_R^2 + (V_L - V_C)^2
  3. So the answer is (c).
