Lightning is a bright flash of electricity produced by a thunderstorm. All thunderstorms produce lightning and are very dangerous. Lightning is an electric current: a natural phenomena and a typical one may transfer 109 J of energy across a potential difference of 50,000,000.00 V during a time interval of about 0.2 s. With the information given, calculate the total amount of charge transferred between the cloud and the ground, the current of lightning bolt, and the average power delivered over 0.2 s time.
