Resistive heating explained in details

Jul 27, 2011 · This resistive heating is the result of "friction," as created by microscopic phenomena such as retarding forces and collisions involving the charge carriers (usually electrons); in formal terminology, the heat corresponds to the work done by the charge carriers in order to travel to a lower potential. This heat generation may be intended by design, as in any heating appliance (for example, a toaster, an electric space heater, or an electric …

Resistance Heating: Methods, Design and Efficiency

ADVERTISEMENTS: Resistance heating is based upon the I2R effect. This method of heating has wide applica­tions such as heat treatment of metals (annealing, harden­ing etc.), drying and baking of potteries, stoving of enameled ware and com­mercial and domes­tic cooking. Tem­perature up to about 1,000°C can be ob­tained in ovens em­ploying wire resistances for heating elements. […]

Joule heating - Wikipedia

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.. Joule's first law, also known as the Joule–Lenz law, 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

Electric Resistance Heating | Department …

Electric resistance heating is energy efficient in the sense that all the incoming electric energy is converted to heat. However, most electricity is produced from coal, gas, or oil generators that convert only about 30% of the fuel's energy into electricity. Because of electricity generation and transmission losses, electric heat is often more expensive than heat produced in homes or businesses that use combustion appliances, such as natural gas, propane, and oil furnaces.
