Answer / munish

if dc applied as I/P. Then nothing o/p.
because T/F is a static which step up down the voltage
without changing the frequency.and it work on
electomagnetic induction ( mutual induction ).so mutual
induction is not possible in dc.

DC voltage has no frequency

Answer / eee

the windings are like inductor, so when dc applied.... the
input rises slowly corresponding to the time constant, during
this period output in secondary corrosponding to the turns
ratio can be observed. once its constant, no change in i/p,
else if current is high magnetic saturation of core occurs....
any no output after the specified time....

Pls Breifly explain about UPS (Inverter,Reserve,Rectifier,Float voltage,Boost voltage).
