    1. The problem statement, all variables and given/known data
    A battery charger is connected to a dead battery and delivers a current of 6.0A for 5.0 hours,keeping the voltage across the battery terminals at 12V in the process.how much energy is delivered to the battery?

    2. Relevant equations

    3. The attempt at a solution
    the answer is 1.3x10^6 Joules but im not getting that.can someone help me please?

    Do you know any other expressions for electrical power and energy?

    Power = Voltage x Current
    Energy = Power x Time.

    Joules of energy is expressed in amp-volt-seconds.

    How many seconds in an hour?
