    Resistance of the resistor, R = 100 Ω

    Supply voltage, V = 220 V

    Frequency, ν = 50 Hz

    The rms value of current in the circuit is given as

    I= (V/R)

    = (220)/ (100)

     = 2.20 A

     The net power consumed over a full cycle is given as:

    P = VI

     = 220 × 2.2 = 484 W

    3Thank You
