R

REPEATER

(1) Another name for an active satellite [17]. (2) Also, a common name for remote radar indicators.


REPELLER

Sometimes called a REFLECTOR. An electrode in a reflex klystron with the primary purpose of reversing the direction of the electron beam [11].


REPERFORATOR

Equipment that converts the incoming TTY signal and stores it on paper tape [17].

REPRODUCTION

The process of converting electrical signals to sound waves. This sound is speech, music, and so on [17].


REPULSION

The mechanical force tending to separate bodies having like electrical charges or like magnetic polarity [1].


RERADIATION

The reception and retransmission of radio waves that is caused by turbulence in the troposphere [10].


RESIDUAL MAGNETISM

Magnetism remaining in a substance after removal of the magnetizing force
[1].


RESISTANCE

(1) The opposition a device or material offers to the flow of current. The effect of resistance is to raise the temperature of the material or device carrying the current. (2) A circuit element designed to offer a predetermined resistance to current flow. A resistance of 1 ohm will allow a current of 1 ampere to flow through it when a potential of 1 volt is applied. [1].


RESISTIVITY

See SPECIFIC RESISTANCE. The reciprocal of conductivity [4].

RESISTOR

The electrical component that offers resistance to the flow of current. It may be a coil of fine wire or a composition rod [1].
