In an AC circuit, V and I are given by V=150 (150 t) volt and I=150 (150 t+ 3 ) amp. The power dissipated in the circuit is

Options

  1. A106 ~W
  2. B150 ~W
  3. C5625 ~W
  4. Dzero

Correct answer

C. 5625 ~W

Step-by-step solution

Given V=150 (150 t) volt I=150 (150 t+ / 3) amp I₀=150 amp V₀=150 volt P= 1 2 V₀ I₀ =0.5 150 150 60^ P=5625 W
