Dictionary of Electrical Engineering

Commonly used terms in the Electrical industry.

ferroresonant transformer
a transformer that is designed to operate as a tuned circuit by resonating at a particular frequency.
resonant
in any circuit or system under excitation, the frequency at which a pair of reactive components cancels (pole or zero) resulting in a natural mode of vibration.
resonant antenna
linear antennas that exhibit current and voltage standing wave patterns formed by reflections from the open end of the wire.
resonant frequency
(1) a frequency at which the input impedance of an device is nonreactive, since the capacitive and inductive stored energy cancel each other.

(2) an oscillation frequency of the modes of a resonator.
