Another nit, transformers don't have to change the voltage at all, isolation transformers usually have a 1 : 1 turns ratio .-- mattb @ 2007-02-17T13 : 26Z

The ideal transformer identity shown in eq . ( 5 ) is a reasonable approximation for the typical commercial transformer, with voltage ratio and winding turns ratio both being inversely proportional to the corresponding current ratio.

If the inductors are wound on the same core and with the same geometry, then this expression is equal to the turns ratio of the two inductors because inductance is proportional to the square of turns ratio.

Cascaded gyrators of gyration resistance \ scriptstyle { R _ 1 } and \ scriptstyle { R _ 2 } are equivalent to a transformer of turns ratio \ scriptstyle { R _ 1 : R _ 2 }.

A gear train is the analogue of an electrical transformer and the h-parameters ( " hybrid " parameters ) better describe transformers because they directly include the turns ratios ( the analogue of gear ratios ).

Tap changers exist in two primary types, no load tap changers ( NLTC ) which must be de-energized before the turn ratio is adjusted and on load tap changers ( OLTC ) which may adjust their turn ratio during operation.

While the output voltage of a flyback converter is theoretically infinite, the maximum output voltage of the forward converter is constrained by the transformer turns ratio \ textstyle N _ \ mathrm { S } / N _ \ mathrm { P }:

The transmission of electric power with alternating current ( AC ) became possible after Lucien Gaulard and John Dixon Gibbs built what they called the secondary generator, an early transformer provided with 1 : 1 turn ratio and open magnetic circuit, in 1881.
