A capacitor is a device that stores electrical energy in an electric field.It is a passive electronic component with two terminals.. Conversely, if the flux path is highly saturated, changes in the armature current cannot contribute to the flux build-up, which means the generators reactance is reduced.

The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.In large parts of the world this is 50 Hz, although in the Americas and parts of Asia it is typically 60 Hz.
