transformer
n 1: an electrical device by which alternating current of one
voltage is changed to another voltage

Transformer \Trans*form"er\, n.
1. One who, or that which, transforms. Specif. (Elec.), an
apparatus for producing from a given electrical current
another current of different voltage.
[1913 Webster]

2. (1990's) a toy consisting of a figure or representation of
an object, constructed of interlocking parts in such a way
that a series of turning or twisting motions of the parts
can transform the object from one type of object to a
different type of object, such as from an animal to an
automobile.
[PJC]

{Multiple transformer}. (Elec.)
(a) A transformer connected in multiple or in parallel
with the primary circuit.
(b) A transformer with more than one primary or more than
one secondary coil.

{Parallel transformer} (Elec.), a transformer connected in
parallel.
[Webster 1913 Suppl.]
