    A 100 ``\Omega`` resistor is connected to a 220 V, 50 Hz ac supply.
    (a) What is the rms value of current in the circuit?
    (b) What is the net power consumed over a full cycle?
    (a) What is the rms value of current in the circuit?
    (b) What is the net power consumed over a full cycle?
    Ans : Resistance of the resistor, R = 100 ``\Omega``

    Supply voltage, V = 220 V

    Frequency, ν = 50 Hz
    (a) The rms value of current in the circuit is given as:


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

    P = VI

    = 220 × 2.2 = 484 W
    (a) The rms value of current in the circuit is given as:


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

    P = VI

    = 220 × 2.2 = 484 W
