principle

Answer / nyo satt paing

The auto transformer is generally used in low power
applications where a variable voltage is
required. The auto transformer is a special type of power
transformer. It consists of only one
winding. By tapping or connecting at certain points along the
winding, different voltages can
be obtained.
