result of being struck by other high-velocity electrons [6].

In a cooling system, the loop that transfers the heat from the heat source, such as electronic equipment, to the primary loop; usually distilled water [18].

The ability of a receiver to select the desired signal and reject unwanted signals [9] [17].

A chemical element with light-sensitive properties that makes it useful as a semiconductor material in metallic rectifiers [7].

In a vacuum tube circuit, the voltage developed by the flow of current through a resistor in the grid or cathode leads [6].

DC generators in which the generator output is fed to the field to produce field excitation [5].

(1) The production of a counterelectromotive force in a conductor when its own magnetic field collapses or expands with a change in current in the conductor [2]. (2) The phenomenon caused by the expanding and collapsing fields of an electron that encircle other electrons and retard the movement of the encircled electrons [10].

Objects that produce their own light [10].
