how step down and step up voltage is occured in transformer..

Answer / murali290

any machine basic working priciple is FARADAYS LAWS of
electro magnetic induction:
1st law:when ever a conductor cuts a magnetic flux an EMF is
induced dyanamically in the conductor.
2nd law:induced emf proportional to flux linkages(N,rate of
change of flux).
based on 1stlaw emf induced in transformer.
stepdown:as secondary turns are low flux linkages is less
hence induced emf is low in secondary camored to primery.
stepup:as secondry turns are high flux linkages is large
hence induced emf is high in secondary camored to primery.

Answer / zakir ali khan

any machine basic working principle is FARADAY LAWS of
electro magnetic induction:
1st law:when ever a conductor cuts a magnetic flux an EMF is
induced dynamically in the conductor.
2nd law:induced emf proportional to flux linkages(N,rate of
change of flux).
based on 1stlaw emf induced in transformer.
step down:as secondary turns are low flux linkages is less
hence induced emf is low in secondary camored to primery.
step up:as secondary turns are high flux linkages is large
hence induced emf is high in secondary camored to primery.

step down:as secondary turns are low flux linkages is less
hence induced emf is low in secondary compere to primery.

step up:as secondary turns are high flux linkages is large
hence induced emf is high in secondary compere to primery.
