In electronics, and in physics more broadly, Joule heating refers to the increase in temperature of a conductor as a result of resistance to an electrical current flowing through it. Two digital voltmeters The field of electronics is the study and use of electrical devices that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. ... When stuff moves. ... Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter. ... It has been suggested that Conductor (power engineering) be merged into this article or section. ... Electrical resistance is a measure of the degree to which an electrical component opposes the passage of current. ... In electricity, current refers to electric current, which is the flow of electric charge. ...

At an atomic level, Joule heating is the result of moving electrons colliding with atoms in a conductor, whereupon momentum is transferred to the atom, increasing its kinetic energy (see heat). Properties For alternative meanings see atom (disambiguation). ... Properties The electron is a subatomic particle. ... In physics, momentum is a physical quantity related to the velocity and mass of an object. ... Kinetic energy (also called vis viva, or living force) is energy possessed by a body by virtue of its motion. ... A red-hot iron rod cooling after being worked by a blacksmith. ...

Joule heating is named for James Prescott Joule, the first to articulate what is now Joule's law, relating the amount of heat released from an electrical resistor to its resistance and the charge passed through it. James Prescott Joule (December 24, 1818–October 11, 1889) was an English physicist, born in Salford, near Manchester. ... Joules law (due to James Prescott Joule) expresses the amount of heat generated by an electrical resistor, and is expressed by the relation by current flowing through a resistor with resistance for a time , and is the heat generated or where is the constant of proportionality, dependent on the...

When similar collisions cause a permanent structural change, rather than an elastic response, the result is known as electromigration. Electromigration is the transport of material caused by the gradual movement of the ions in a conductor due to electrical current. ...
