draw a labelled diagram of an ac generator. obtain the expression for the end induced in the rotating coil of N turns each of cross-sectional area A ,in the presence of a magnetic field B .
Dear Student,
AC Generator:
Principle: It works on the principle of Faraday's law of electromagnetic induction. Whenever a coil is rotated in a uniform magnetic field about an axis perpendicular to the field, the magnetic flux linked with coil changes and an induced emf is set up across its ends.
