Electric heat is produced by converting electrical energy to heat. This is done by placing a known resistance of a particular material an electric circuit. The resistance has relatively few free electrons and does not conduct electricity easily. Resistance to electron flow produces heat at the point of resistance. One type of material… Read More: Introduction to Electric Heat an Overview »
