In the series L-C-R circuit shown, the impedance is

Options

  1. A200
  2. B100
  3. C300
  4. D500

Correct answer

D. 500

Step-by-step solution

Here, L=1 H , C=20 F , R=300 aligned & X_L=2 f L=2 ( 50 ) 1=100 & X_C= 1 2 f C = 1 2 ( 50 ) 20 10⁻⁶ =500 aligned Impedance, aligned Z & = R^2+ (X_C-X_L )^2 & = (300)^2+(400)^2 =500 aligned
