Solution

Solution:
No, the lightning conductor won’t be effective if it is left hanging in the air.
[1 mark]

The purpose of a lightning conductor is to carry charges to the Earth. This is why a metal plate is connected to its end which is buried in the ground. If the end is hanging in the air, the charges won’t get transferred to the Earth in case of a lightning strike.
