Question

What is the objective of providing earthing in lightning conductors?

• A. It enables the charges to be distributed to the earth
• B. To provide a high resistance path to prevent leakages to the ground.
• C. To attract lightning
• D. To dissipate the heat of a lightning strike

Answer 1

The correct option is A

It enables the charges to be distributed to the earth

The earth acts as a giant sink which can take any amount of charges provided to it. When we provide adequate earthing to lightning conductors, it transfers the charge from the lightning to the ground safely bypassing the building and its occupants.
