Question 19

If the materials used for constructing a building were good conductors, do you think lightning will strike the building? Will the lightning conductor be still required to be installed in the building?

Solution

Lightning will not strike the building because charge separation cannot take place in conductors. All the lightning falling on the building will reside on the surface of the building.
So, there is no need of installing any lightning conductor because all the work of lightning conductor is done by the conducting material itself.
