Joule heating
Joule heating
Joule heating, also known as ohmic heating and resistive heating, is the process by which the passage of an electric current through a conductor releases heat. The amount of heat released is proportional to the square of the current such that
This relationship is known as Joule's first law or Joule–Lenz law.[1] Joule heating is independent of the direction of current, unlike heating due to the Peltier effect.
