Explanation:
Joule heating, also known as resistive, resistance, or Ohmic heating, is the process by which the passage of an electric current through a conductor produces heat.
A coiled heating element from an electric toaster, showing red to yellow incandescence
Joule's first 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:
{\displaystyle P\propto I^{2}R}{\displaystyle P\propto I^{2}R}
Joule heating affects the whole electric conductor, unlike the Peltier effect which transfers heat from one electrical junction to another.
