Joule heating, also known as resistive, resistance, or Ohmic heating, is the process by which the passage of an electric currentthrough a conductor produces heat.
Joule's first law (also just Joule's law), also known as the Joule–Lenz law,[1] states that the power of heating generated by an electrical conductor is proportional to the product of its resistance and the square of the current:
Joule heating affects the whole electric conductor, unlike the Peltier effect which transfers heat from one electrical junction to another.
