Dear student,

An electrical discharge characterized by a corona and occurring when one of two electrodes in a gas has a shape causing the electric field at its surface to be significantly greater than that between the electrodes.

a luminous discharge which occurs when the applied voltage is high enough (5000 volts or more) to cause partial ionization of the surrounding gas

hope this helps.
