How long can a lightning strike power a light bulb? The most powerful type of lightning strike is the positive polarity strike. It contains 10 billion Joules of energy, which is 10x more powerful than a negative polarity strike. Follow the assumptions below to answer these three questions about lightning and light bulbs.

Assumptions:

Lightning Energy = 10 billion Joules (10*10⁹ J)

Incandescent iight bulb wattage = 60 W

LED light bulb (60 W equivalent) = 6 W

1 W = 1 J/s

1. How long (in days) could the energy from a lightning strike power a 60 W incandescent light bulb?Since only 0.1% of all the energy in this strike is electrical, how long could just the electrical part of the energy from the strike power a 60 W incandescent light bulb?
