  • A transformer that has a single winding, which is tapped at different points to provide both the primary and secondary circuits.


Electronics and Electrical Engineering
  • A transformer that has a single winding, tapped at intervals, rather than two or more independent windings. Part of the winding is thus common to both primary and secondary circuits (see diagram). The voltage V2 across a tapped section is related to the total applied voltage V1 by

    V2V1n2n1

    where n2 is the number of turns in the tapped section and n1 the total number in the winding.
