Jabarkan Trafo résonansi dari Trafo dalam bahasa sunda

A resonant transformer is one that operates at the resonant frequency of one or more of its coils and, usually, an external capacitor.  The resonant coil, usually the secondary, acts as an inductor, and is connected in series with a capacitor.  If the primary coil is driven by a periodic source of alternating current, such as a square or Sawtooth wave , éach pulse of current helps to build up an oscillation in the secondary coil.  Due to resonance, a very high voltage can develop across the secondary, until it is limited by some process such as electrical breakdown.  These devices are therefore used to generate high alternating voltages.  The current available from this type of coil can be much larger than that from electrostatic machines such as the Van de Graaff generator and Wimshurst machine. They also run at a higher operating temperature than standard units.
