tank circuit
Parallel resonant circuit containing only a coil and a capacitor. Both the coil and capacitor store electrical energy for part of each cycle.

tantalum capacitor
Electrolytic capacitor having a tantalum foil anode. Able to have a large capacity in a small package.

Electrical connection to some point other than at the ends of a resistor or inductor.

Nonunifrom distribution of resistance per unit length throughout the element of a potentiometer.

Expert in troubleshooting circuit and system malfunctions. Along with a thorough knowledge of test equipment and how to use it to diagnose problems, the technician is also familiar with how to repair or replace faulty components. Technicians basically translate theory into action.

Communicationbetween two points by sending and receiving a series of current pulses either through wire or by radio.

Transmission of instrument readings to a remote location either by wire or by radio.

Apparatus designed to convert sound waves into electrical waves which are sent to and reproduced ata distant point.

telephone line
Wires existing between subscribers and central stations in a telephone system.

Telecommunications system involving the transmission of speech information, allowing two or more persons to communicate verbally.

Electric typewriter that like a teleprinter can produce coded signals corresponding to the keys pressed or print characters corresponding to the coded signals received.

System that converts both audio and visual information into corresponding electrical signals which are then transmitted through wires or by radio waves to a receiver which reproduces the original information.

Teletypewriter exchange service.

temperature coefficient of frequency
Rate at which frequency changes with temperature.

(T) Metric prefix that represents 1012.

Point at which electrical connections are made.

(T) Unit of magnetic flux density. (1 tesla = 1 Wb/m2).

Sequence of operations intended to verify the correct operation or malfunctioning of a piece of equipment or system.

thermal relay
Relay activated by a heating element.

thermal runaway
Problem that can develop in an amplifier when an increase in temperature causes an increase in collector current. The increase in collector current causes a further increase in temperature and so on. Unless the circuit is designed to prevent this condition, the device can be driven into saturation.

thermal stability
The ability of a circuit to maintain stable characteristics in spite of increased temperature.

Temperature sensitive semiconductor that has a negative temperature coefficient of resistance. As temperature increases, resistance decreases.

Temperature transducer consisting of two dissimilar metals welded together at one end to form a junction that when heated will generate a voltage.

Relating to the measuring of temperature.

Device that opens or closes a circuit in response to changes in temperature.

Thevenin's theorem
Theorem that replaces any complex network with a single voltage source in series with a single resistance.
