Q. Non uniform distribution of variable currents in solid conductors resulting in an increase in the current density near the surface :

A
Corona
B
Skin effect
C
Eddy current
D
Joule effect
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.
