T
THERMAL RUNAWAYA 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 ELEMENTA 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 ELEMENTA single circuit breaker trip element that combines the action of a thermal and a magnetic trip element [3]. |
THERMIONIC EMISSIONEmission 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]. |
THERMOCOUPLEA junction of two dissimilar metals that produces a voltage when heated [1]. |
THERMOCOUPLE METER MOVEMENTA 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]. |
THERMOPLASTICA 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]. |
THETAThe Greek letter (θ) used to represent phase angle [2]. |
THICK FILM COMPONENTSPassive circuit components (resistors and capacitors) having a thickness of 0.001 centimeter [14]. |
