what will happen at secondary side of transformer if i
increase voltage at primary side?while
V1*I1=V2*I2

will secondary voltage or current increase?

Answer Posted / anand kumar c

If you increase the voltage at the primary of the
transformer, then definitely at the secondary side voltage
increases, but it will cause loading of the winding. so you
should not increase voltage at the primary side beyond the
rated voltage.

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.
