RELUCTANCE. A measure of the opposition that a material offers to magnetic lines of force.
REMOTE-CUTOFF TUBE. An electron tube in which the control grid wires are farther apart at the centers than at the ends. This arrangement allows the tube to amplify large signals without being driven into cutoff. [VARIABLE-MU TUBE].
REPEATER. A station that receives a signal [on one frequency] and re-transmits the signal [on another frequency] over the air. A device that regenerates the incoming signal to the original signal level, and than retransmits that signal to increase the distance the signal can travel.
REPELLER. [REFLECTOR]. An electrode in a reflex klystron with the primary purpose of reversing the direction of the electron beam.
REPRODUCTION. The process of converting electrical signals to sound waves. This sound is speech, music, and so on.
REPULSION. The mechanical force tending to separate bodies having like electrical charges or like magnetic polarity.
RERADIATION. The reception and retransmission of radio waves that is caused by turbulence in the troposphere.
RESIDUAL MAGNETISM. Magnetism remaining in a substance after removal of the magnetizing force.
RESISTANCE. 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. 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.
RESISTIVITY. The reciprocal of conductivity.
RESISTOR. The electrical component that offers resistance to the flow of current. It may be a coil of fine wire or a composition rod. [Resistor Manufacturers]
RESOLVER. A rotary, electromechanical device used to perform trigonometric computations by varying the magnetic couplings between its primary and secondary windings. It is generally used in circuits that solve vector problems, such as analog computers and conversion equipment. The resolver solves three different type problems: (1) Resolution - separating a vector into two mutually perpendicular components; (2) Composition - combining two components of a vector to produce a vector sum; and (3) Combination - the process of resolution and composition taking place simultaneously.
