  1. Apr 2, 2009 #1
    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
    R=I^2RT



    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?
