Answer Posted / jawad
i found my answer myself.there is nothing to do with
linearity or non linearity.
ohm law states that "voltage is directly propotional
current IF RESISTANCE IS KEPT CONSTANT.
WHAT HAPPENED HERE IS WE DID NOT SATISFY THE CONDITION OF
OHM LAW BY NOT KEEPING THE RESISTANCE CONSTANT.
so in transformer (considering only primary side,u can also
apply it on secondary), when u step up the voltage by tap
changer, actually u r increasing the no of turns which
alternatively means u r increasing the length of total
winding and hence INCREASINGING THE RESISTANCE AND BECAUSE
OF INCREASE IN RESISTANCE, THE CURRENT DECREASES.
HOPE IT WILL SATISFY U PEOPLE.BUT FOR SURE THERE IS NO
OTHER ANSWER.
