Question

Working of ab AC generator...


explain in easy way with diagrams

Answer 1

Principle-
AC generator works on the principle of electromagnetic induction. Whenever amount of magnetic flux linked with coil changes , an emf induced in the coil .

It lasts so long as the change in magnetic flux through the coil continues .

Working-
When a closed armature coil rotates in a uniform magnetic field with its axis perpendicular to the magnetic field , the magnetic flux linked with the loop changes and emf induces in the coil .Let initially angle between area vector of coil and magnetic field B is 0° .Thereafter , AB comes downward and CD upward then by Fleming's right hand rule induced current flows from B to A .

During the next half revolution , when CD comes downward and AB upward then current flows from C to D
