In series L C R circuit, the phase difference between applied voltage and current is

Options

  1. Apositive when X_L>X_C
  2. Bpositive when X_C>X_L
  3. C90^
  4. D0^

Correct answer

A. positive when X_L>X_C

Step-by-step solution

In series LCR circuit, the phase angle is given by = X_L-X_C R When X_L>X_C , tan is positive. Therefore the phase difference is positive.
