    1. The problem statement, all variables and given/known data
    During a lightning strike, 30C of charge may move through a potential difference of 1.0 x 10^8 V in 0.02s. The total energy released by this lightning bolt is ______ J.

    2. Relevant equations

    I = q/t

    3. The attempt at a solution

    I'm really not sure what to do here...I have all three values in the equasion..obviously I'm doing something very, very, wrong. I think I'm missing an equation. Help me, please?
