Joule heating
Türkçe: Joule ısınması
The conversion of electrical energy into heat, P = I²·R, as current flows through a conductor.
// EXPLANATION
Heat is proportional to the square of the current: doubling the current quadruples the heat. That is why transmission voltage is raised, and why reducing current or resistance is fundamental in power supplies and connectors.

// RELATED TERMS
Electrical resistanceThe opposition a material offers to current flow; by Ohm's law R = V / I, measured in ohms.
Contact resistanceThe extra resistance at the point where two conductive surfaces meet, caused by surface roughness and oxidation.
High voltageThe voltage class used to carry energy from power plants to distant loads with low losses, covering levels such as 154 kV and 380 kV on the Turkish transmission grid.
