Electronics (Mike Jaroch)

(1) A semiconductor device whose resistance varies with temperature [4]. (2) A type of bolometer characterized by a decrease in resistance as the dissipated power increases [16].

A junction of two dissimilar metals that produces a voltage when heated [1].

A meter movement that uses the current induced in a thermocouple by the heating of a resistive element to measure the current in a circuit; used to measure ac or dc [3].

A synthetic mixture of rosins that is flexible and used as an insulting material.
Generally used as an insulator for low- and medium-range voltages [4].

The Greek letter (θ) used to represent phase angle [2].

Passive circuit components (resistors and capacitors) having a thickness of 0.001 centimeter [14].

Passive circuit elements (resistors and capacitors) deposited on a substrate
to a thickness of 0.0001 centimeter [14].

(3D)—A radar set that measures the range, bearing and altitudes of a target [18].

An array with two parasitic elements (reflector and director) and a driven
element [10].

In a switch, the number of different circuits each pole can control; for example, single throw and double throw [3].
