Electronics (Mike Jaroch)

In a switch, the number of breaks refers to the number of points at which the switch opens the circuit; for example, single break and double break [3].

The phenomenon occurring in a reverse-biased semiconductor diode. The start of the phenomenon is observed as a transition from a high dynamic resistance to one of substantially lower dynamic resistance. This is done to boost the reverse current [7].

The name given to the potentiometer used to vary the potential applied to the
control grid of a CRT [6].

An array in which the direction of maximum radiation is perpendicular to the
plane containing the elements [10] [18].

Sliding contacts, usually carbon, that make electrical connection to the rotating part of a motor or generator [5].

A voltage amplifier used between the oscillator and power amplifier [12].

An amplifier that isolates one circuit from another. It decreases the loading effect on an oscillator by reducing the interaction between the load and the oscillator [9] [18].

A permanently mounted device that is used expressly for testing an equipment or system [14].

The input resonant cavity in a conventional klystron oscillator [11].

In a velocity-modulated tube, the grid that concentrates the electrons in the electron beam into bunches [11].
