Energy!?! Please help!! (ToT) 1. The problem statement, all variables and given/known data A bolt of lightning corresponding to about 20C descends through a potential difference of upwards of 150MV. How much energy is involved? Incidently, at any one time there might be 2000 thunderstorms rolling over the Earth with 100 lightning bolts flashing every second! 2. Relevant equations change in V= PE/q 3. The attempt at a solution I know MV is 1000000V...but I have no idea how to solve this question...T_T please help ASAP.. Thank you very much!!
