Answer / pritam khan

Using transformer,we step-up or step-down ac voltage,which depends on no. of turns,which again depends on the flux linkage or flux cut by primary & secondary.But,using resistance,that obeys Ohm's law,we can operate on dc circuits and on those ac circuits where phase difference remains 0.Using resistance,with any other phase differnce, cannot be materialized for the above-asked purpose.

Answer / pankaj

transformer has 2 side i.e. primary and secondary. so power
input supply in and output has taken from 2ndry side so
there is no any phyical connection between them.. if
primary side gets sorted then there is no effect on 2ndry
output... means circuit is safe..
