transformer

 [trans-for´mer]
an induction apparatus for changing electrical energy at one voltage and current to electrical energy at another voltage and current, through the medium of magnetic energy, without mechanical motion.
step-down transformer one for lowering the voltage of the original current.
step-up transformer one for raising the voltage of the original current.

transformer

[-fôr′mər]
Etymology: L, transformare, to change shape
an electric apparatus that changes alternating current of one voltage into a different voltage of the same frequency.

transformer,

n an electrical device that increases or reduces the voltage of an alternating current by mutual induction between primary and secondary coils or windings.
transformer, auto-,
transformer, Coolidge filament,
n.pr a step-down transformer that reduces line voltage of 110 volts to 12 volts, which in turn heats the tungsten filament of the Coolidge tube for the production of electrons.
transformer, step-down,
n a transformer in which the secondary voltage is less than the primary voltage.
transformer, step-up,
n a transformer in which the secondary voltage is greater than the primary voltage.
