    Question

    An electric device draws a current of 5" " A when connected to a 220" " V supply. The power of the electric device is:

    A.

    1.1" " kW

    B.

    0.44" " kW

    C.

    110" " W

    D.

    440" " W

    Correct option is A

    Given:

    • V= 220V,
    • I=5AI = 5 \, \text{A} I=5A

    Formula used:

    P =  V × I

    Where:

    • ‘P’ is the power (in watts, W),
    • ‘V’ is the voltage (in volts, V),
    • ‘I’ is the current (in amperes, A)

    Now, substitute the values into the formula:

    P= 220V× 5A= 1100W

    To convert watts (W) to kilowatts (kW), you divide the power in watts by 1000:

    So, for 1100 W= 1100W1000\frac{1100W}{1000}= 1.1kW​

    Thus the correct answer is (A)

    P
