• 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. It was first studied by James Prescott Joule in 1841. Joule immersed a length of wire… …   Wikipedia

• Joule's laws — are a pair of laws concerning the heat produced by a current and the energy dependence of an ideal gas to that of pressure, volume, and temperature, respectively. Joule s first law, also known as the Joule effect, is a physical law expressing the …   Wikipedia

• Heating element — A heating element converts electricity into heat through the process of Joule heating. Electric current through the element encounters resistance, resulting in heating of the element. Most heating elements use Nichrome 80/20 (80% nickel, 20%… …   Wikipedia

• Dielectric heating — A microwave oven, which uses dielectric heating to cook food Dielectric heating, also known as electronic heating, RF heating, high frequency heating and diathermy, is the process in which a high frequency alternating electric field, or radio… …   Wikipedia

• Electric heating — is any process in which electrical energy is converted to heat. Common applications include heating of buildings, cooking, and industrial processes. An electric heater is an electrical appliance that converts electrical energy into heat. The… …   Wikipedia

• Induction heating — is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, where eddy currents are generated within the metal and resistance leads to Joule heating of the metal. An induction heater (for any… …   Wikipedia
