Answer / amritpal singh sidhu

The principle of Alternator is Electromagnetic Induction,
i.e. whenever a conductor cuts the magnetic flux an emf
will induce in the same conductor.
Same process is done in alternators, as we rotate the rotor
of the alternator, due to that its conductors cut the
magnetic flux & emf is induced in the rotating conductors,
which is collected with the help of slip-rings......!

Answer / zia abbas

When conductor cut the magnetic feild then emf produced in
the same conductor when conductor cut the line of forces at
90 degree at time maximum emf produced in that conductor
and during that time when line of forces and conductor are
paralled to each other then at that time creating emf will
be zero

any one have papers of hpcl or sailof ELECTRICAL ENGG.
