In an RLC series circuit shown in figure, the readings of voltmeters ( V ₁ ) and ( V ₂ ) are 100 V and 120 V respectively. The source voltage is 130 V. For this situation mark out the correct statement(s). (a) Voltage across resistor, inductor and capacitor are (50 ~V , 86.6 ~V ) and 206.6 V, respectively (b) Voltage across resistor, inductor and capacitor are (10 ~V , 90 ~V ) and 30 V, respectively (c) Power factor

Options

  1. Aa,c, d
  2. Bb, c, d
  3. C( c , d )
  4. DNone

Correct answer

A. a,c, d

Step-by-step solution

( aligned & V₁= V_R^2+V_L^2 =100 (1) & V_C-V_L=120 (2) & 130= V_R^2+ (V_L-V_C )^2 V_R=50 ~V & V_L=50 3 V=86.6 ~V ~ &~ V_C=206.6 ~V & = V_R 130 = 5 13 aligned )
