Answer Posted / raviranjan kumar
An auto trnsformer with only one winding wound on a
laminated core. A part of this winding is common to
both primary and secondary side .
in an ordinary transformer,the primary and secondary
winding are electricallyfrom each other but connected
magnetically.
In an auto transformer the primary andsecondary wind-
ing are connected magnetically and electrically.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened. Why does the strand conductor of Electrical power transmission line make twist?

if we look on phasor of the transformer vaoltage is 180 oppsite at primary and the secondary so to improve a power factor is secondary should kept negative to improve it primary side means is -.90 became +.90 at other side
