Solution:

• Skin effect is the increase in the current density near the surface of solid conductors due to non uniform distribution of variable currents.

• Joule effect refers to the heating that occurs when an electric current flows through a resistance

• Corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is electrically charged.

• Eddy currents are loops of electrical current induced within conductors by a changing magnetic field in the conductor according to Faraday’s law of induction.
