The conductor which is fixed on the top of the building to protect the buildings from the damage by lightning. The conductor consists of several sharp metal spikes connected to a thick copper strip. The other end of the copper strip is fixed to a metal plate buried inside the ground. The process is called earthing. The conductor hoe works on the principle of induction. Whenever a charged cloud pass by the building, the conductor gets charge x opposite to that of the cloud through the process of induction. Now this acquired charge moves to the earth through the earthing system.
