An AC (non-polarized), usually high voltage capacitor that is connected in
parallel with an inductive Motor (and very close to the motor, or other
inductive load) to help reduce Reactive Power (Magnetizing AMPS)
which do no real work but only cause extra heat in the wiring and motor
as there is a Lagging Current Phase Angle created by an Inductor and a
Leading Current Phase Angle created by a capacitor which helps correct
the impedance mismatch between line and load.
