Answer Posted / shiny ayub
An autotransformer is an electrical transformer with only
one winding. The winding has at least three electrical
connection points called taps. The voltage source and the
load are each connected to two taps. One tap at the end of
the winding is a common connection to both circuits (source
and load). Each tap corresponds to a different source or
load voltage. In an autotransformer a portion of the same
winding acts as part of both the primary and secondary
winding.
