They have developed a technology capable of storing the energy released in electrical storms where 92 lightning strikes are produced every second. In a simplified way, lightning occurs when the potential difference between the cloud and the planet's surface reaches at least 2.6 cross times 10 to the power of 7 volts. The electrical currents generated in lightning are about 3.4 cross times 10 to the power of 4 amperes on average. Determine the average power of 92 lightning strikes produced with these values of potential difference and an electric current.
