Question

Why is one end of a lightning conductor buried deep under the ground?

• A. Earth can absorb any amount of charges.
• B. It helps to create a return path for the charges
• C. Earth is a positively charged body
• D. The Earth is an insulator

Answer 1

The correct option is A

Earth can absorb any amount of charges.

Earth is an excellent sink for charges and will absorb any amount of charges that come from the lightning via the lightning conductor; Earth has an infinite amount of both positive and negative charges. Adding a lightning worth of electrons makes no difference to the state of the earth.
