Electricity always attempts to travel to the ground/earth and looks for the shortest path and will take the path of least resistance to reach the ground.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Electricity always attempts to travel to the ground/earth because the ground is a good conductor of electricity. It looks for the shortest path and will take the path of least resistance to reach the ground. This is why lightning strikes often hit tall objects like trees or buildings, as they provide a more direct path to the ground.
