Electronics (Mike Jaroch)

A circuit breaker trip element that uses the increasing magnetic attraction of a coil with increased current to open the circuit [3].

The property possessed by certain materials by which these materials can exert
mechanical force on neighboring masses of magnetic materials and can cause currents to be induced in conducting bodies moving relative to the magnetized bodies [1].

An electron tube that provides a high power output. Theory of operation
is based on interaction of electrons with the crossed electric and magnetic fields in a resonant cavity [18].

Work done to correct, reduce, or counteract wear, failure, and damage to equipment [16].

The lobe in which the greatest amount of radiation occurs [10].

The mobile charge carriers (hole or electron) which are predominate in a
semiconductor material; for example, electrons in an N-type region [7].

A quarter-wave antenna that is operated with one end grounded and is positioned perpendicular to the earth [10].

An interval during which a signal is present. Also the presence of an RF signal in cw keying. The key-closed condition (presence of data) in communications systems [12].

The state where a circuit is closed and current flows in teletypewriter operation [17].

A device used to deposit materials on a substrate in the desired pattern [14].
