Joule Heating
Electronic systems work based on current and voltage signals. Current is the a flow of charged particles through the material and these particles (electrons or holes), interact with the lattice of the crystal losing its energy which is released in form of heat. Joule Heating is a predominant mechanism for heat generation in integrated circuits and is an undesired effect in most of the cases. For an ohmic material, it has the form:
Where is the current density in, is the specific electric resistivity in and is the generated heat per unit volume in .

Famous quotes containing the word heating:
“If the factory people outside the colleges live under the discipline of narrow means, the people inside live under almost every other kind of discipline except that of narrow means—from the fruity austerities of learning, through the iron rations of English gentlemanhood, down to the modest disadvantages of occupying cold stone buildings without central heating and having to cross two or three quadrangles to take a bath.”
—Margaret Halsey (b. 1910)
