    Question

    A bulb draws a current of 3 A when connected to a battery of 12 V. The power of the bulb is:

    A.

    4 W

    B.

    18 W

    C.

    36 W

    D.

    12 W

    Correct option is C

    Given:

    Voltage V = 12V

    Current I = 3A

    Formula used:

    P= V × I (Where P is the Power(W))

    Solution:

    Substitute the value of voltage and current

    P = 12V ×3A = 36W

    P= 36W

    Thus the correct answer is (C)
