please explain corona discharge and dielectric breakdown of air in short simple words protects a person from lightning strikes if he is in a car v Except for spherical surfaces the charge is not distributed uniformly on the surface of a conductor At the sharp points or edges the surface charge density a is very high and hence the electric field 6 E becomes very strong The air around such sharp points may become ionised producing 0 the corona discharge in which the charge jumps from the conductor to the air because of the dielectric breakdown of the air
