Question

During lightning strike, which of the following happen/s?

• A. Non metals are magnetised.
• B. A large amount of heat will be generated
• C. Huge amount of charge flows.
• D. Sound is heard after lightning strike.

Answer 1

Answer: (B), (C), (D)

Sound is heard after lightning strike.

During lightning strike, the accumulated charges in the cloud induce opposite charges on the Earth. Insulating air breaks down and hence huge amount of charge flows. Enormous amount of heat is generated due to this high charge flow(current). This is followed by production of sound which is heard after the lightning flash as light travels faster than sound.
