    Given :

    Current flow light bulb = 2.5\sf{A}

    Resistance of light bulb = 3.6Ω

    To Find :

    We have to find voltage of battery.

    Solution :

    ➠ As per ohm’s law, current flow through a conductor is directly proportional to the applied potential difference.

    ➝ V ∝ I

    ➝ V = I × R

    Where, R is the resistance of conductor.

    ⇒ V = I × R

    ⇒ V = 2.5 × 3.6

    ⇒ V = 9 volt
