Power, Power Factor & Wattless Current

In series LCR circuit, resistance is 18 Ω18\ \Omega and impedance 33 Ω33\ \Omega. An r.m.s. Voltage of 220220 V is applied across the circuit. The true power consumed in a c. circuit is

Show answer and solution

Answer: (d)

  1. True power P=Irms2R=V2RZ2P = I_{rms}^2R = \frac{V^2R}{Z^2}
  2. P=2202×18332=48400×181089P = \frac{220^2\times18}{33^2} = \frac{48400\times18}{1089}
  3. P=800 WP = 800\text{ W}
  4. So the answer is (d) 800 W.
