    Thus, the energy stored by a 50 Ampere minute battery is found to be 36 KJ.

    Explanation:

    The power delivered by a battery is given by the formula:

    P = VI

    where,

    P = Power Delivered by battery in 1 second

    V = Voltage of battery = 12 volt

    I = Current stored in battery

    But, if we multiply both sides of equation by time (t), then:

    Pt = VIt

    where,

    Pt = Power x Time = E = Energy Stored = ?

    It = Rating of Battery = (50 A. min) (60 sec/min) = 3000 A. sec

    Therefore,

    E = (12 volt) (3000 A. sec)

    E = 36000 J = 36 KJ

    Thus, the energy stored by a 50 Ampere minute battery is found to be 36 KJ.
