Answer / suresh
process by which a current,develops from an electrode with a
high potential in a neutral fluid, usually air, by ionizing
that fluid so as to create a plasma around the electrode.
The ions generated eventually pass charge to nearby areas of
lower potential, or recombine to form neutral gas molecule,
then produce a ight arround the conductor is known as
corona.......

Answer / yaswanth
Basically it happens due to 3causes.1)Bimetalic materials
which is connected together.2)weather position.3)The ele.
current which is passed through it is getting heat on the
conductor&it get release the ions arround it which is
created a layer on that.
