Question

How does electric discharge in lightning occur if air is a bad conductor of electricity?

• A. Water particles in the air help in flow of charges.
• B. Air becomes good conductor when lightning occurs.
• C. Magnitude of accumulated charges in clouds is very high.
• D. All of these

Answer 1

The correct option is C

Magnitude of accumulated charges in clouds is very high.

When the magnitude of the accumulated charges becomes very large, the air which is normally a poor conductor of electricity is no longer able to resist their flow.
