One day on a particularly stormy night, a science student is watching the rain and thinking about all the homework they have to do. Just then a bolt of lightning discharges 21 C from one cloud to a power line. The student was able to use their iPhone to measure the potential difference to be 15,050 volts. With this data, how much energy is lost by the cloud and gained by the power line? b C Od 316,050 J 442,470 J 94,815J 221,235J
