In an L-C-R series circuit, the values of R, X_L and X_C are 120 , 180 and 130 , what is the impedance of the circuit?

Options

  1. A120
  2. B130
  3. C180
  4. D330

Correct answer

B. 130

Step-by-step solution

Given, R=120 _L=180 , X_C=130 The impedance of L-C-R circuit Z= R^2+ (X_L-X_C )^2 aligned Z & = (120)^2+(180-130)^2 & =130 aligned
