T

THERMAL RUNAWAY

A conduction that exists when heat causes more electron-hole pairs to be
generated, which, in turn, causes more heat and which may eventually cause diode destruction [7].


THERMAL TRIP ELEMENT

A circuit breaker trip element that uses the increased bending of a
bimetallic strip caused by increased current to open a circuit [3].


THERMAL-MAGNETIC TRIP ELEMENT

A single circuit breaker trip element that combines the action of a thermal and a magnetic trip element [3].


THERMIONIC EMISSION

Emission of electrons from a solid body as a result of elevated temperature [6].


THERMISTOR

(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].


THERMOCOUPLE

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

THERMOCOUPLE METER MOVEMENT

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].


THERMOPLASTIC

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].


THETA

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

THICK FILM COMPONENTS

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