Potential difference charge and Energy - Equation

  1. Jul 17, 2010 #1
    1. The problem statement, all variables and given/known data
    If the potential difference between a cloud and the ground is about 13MV , how much charge is transferred in a lightning bolt that releases 1.3GJ of energy?

    2. Relevant equations

    3. The attempt at a solution

    1st can someone check my conversion - P.d=13*10^6V and E=13*10^9J
    The main problem I have is that I dont know the equation relating E, P.V and q or if it exists... can someone please give me a hand... thanks
