If a 1.5V battery stores 5.0kj of energy,for how many minutes could it sustain a current of 1,2A?

  • Physics -

    Energy = Power*time

    Power = I^2*r = I*V = 1.5*1.2

    5 * 10^3 = 1.5*1.2*time

    solve for time. Your answer will be in the SI units of seconds; divide this answer by 60 sec/min to convert the answer to minutes
