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?
No, lightning will not strike the building because:
i. The charge separation cannot take place in conductors.
ii. The lightning falling on the building will remain on the surface of the building.
iii. Therefore, it will not strike the building.
No, there is no need to install the lightning conductor in the building because
i. The conducting material will act as a lightning conductor itself.
ii. It will protect the building from the effect of lightning.
