In an a.c. circuit containing L, C and R in series, the ratio of apparent power to the true power is (Z= impedance of the circuit and R= resistance )

Options

  1. ARZ
  2. BZ R

Correct answer

3

Step-by-step solution

Apparent power is given by P_ app = V_ rms I_ rms True power is given by P_ true = V_ rms I_ rms The ratio of apparent power to true power is P_ app P_ true = V_ rms I_ rms V_ rms I_ rms = 1 In a series LCR circuit, the power factor is = R Z Substituting this value, the ratio becomes Z R Answer: Z R
