ELECTROMAGNETIC RADIATION

The radiation of radio waves into space [10].

ELECTROMAGNETISM

The generation of a magnetic field around a current-carrying conductor [2]
[3].

ELECTROMOTIVE FORCE

The force (voltage) that produces an electric current in a circuit [2].

ELECTRON

The elementary negative charge that revolves around the nucleus of an atom [1].

ELECTRON GUN

An electrode of a CRT that is equivalent to the cathode and control grid of
conventional tubes. The electron gun produces a highly concentrated stream of electrons [6].

ELECTRON ORBITAL MOVEMENT

The movement of an electron around the nucleus of an atom [11].

ELECTRON SHELL

A group of electrons which have a common energy level that forms part of the
outer structure (shell) of an atom [1].

ELECTRON SPIN

The movement of an electron around its axis [11].

ELECTRONIC COUNTER-COUNTERMEASURES (ECCM) CIRCUITS

See ANTIJAMMING CIRCUITS [18].

ELECTRONIC FREQUENCY COUNTER

An instrument that counts the number of cycles (pulses) occurring during a precise time interval [18].
