उत्तर
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 works on the principle of induction. Whenever a charged cloud passes 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.
