electro-, electr-, electri-

A collective term for all natural electrical phenomena of the earth, including atmospheric electricity.

Involving or produced by thermoelectricity; that is, electrical phenomena occurring in conjunction with a flow of heat

An electronic heat pump used to produce cooling with a thermoelectric effect, consisting of a thermocouple with its "cold" end in the chamber to be cooled and its "hot" end in an outside heat sink.

1. An electrical current generated in a thermopile.
2. Electricity generated by heat.
3. Electricity produced by the direct action of heat or the direct conversion of heat into electricity; such as, in a thermocouple.

An electron emitted by a very hot object.

An electrical charge produced by friction between two objects; such as, rubbing silk on a glass surface.

In physics, electrical charges produced by friction between two surfaces; static electricity.

Frictional electricity was supposedly known to the ancient Greeks, particularly Thales of Miletus, who observed about 600 B.C. that when amber was rubbed, it would attract small bits of matter. The term "frictional electricity" gave way to "triboelectricity," although since "tribo" means "to rub," the newer term does little to change the concept.

The separation of electrical charges through surface friction.

1. A potential gradient that arises across the interface between the boundary liquid layer in contact with a solid and the movable diffuse layer in the body of the liquid.
2. Electrokinetic potential refers to the potential developed across any interface separating two phases as a result of the accumulation of electrons in one phase and the loss of electrons in the other.
3. Bioelectric potential refers to the difference of electric potential between the inside and the outside of a cell.
