REACTANCE
The opposition to an alternating current presented by inductance, capacitance, or a combination of the two. Reactance is measured in "ohms" and is represented by the letter "X".
RESISTANCE WELD
Procedure involving pressure sealing with electricity and backfilling with nitrogen to force out oxygen and moisture. This results in superior aging characteristics.
RESISTORS
A component used to introduce resistance into a circuit.
RESONANT FREQUENCY
The natural frequency at which a circuit oscillates or a device vibrates. Abbreviated as "Fr" or "fr".
RESONANCE
The creation of vibrations in a system by the application of a periodic force. The state which exists when the frequency of the applied force is equal to the natural frequency of the system.
RESONATOR
A body that is capable of being set into resonance by the application of a periodic force.
