Question

In a small bicycle dynamo, a coil of 100 turns is wound in two diametrically opposite slots of the armature. If
the armature is driven at a speed of 1,000 rpm in a uniform magnetic field of 0.05 Wb/m2
normal to the axis

of the armature, Find (a) the equation for the emf induced in the coil, (b) maximum value of the induced emf.
The mean area of the coil is 10 cm2

Answer 2

G00GLE pe PDF h jaake dekh :) !! xD

In a single phase AC generator, the armature conductors are connected in series so as to form a single circuit which generates a single-phase alternating emf and hence it is called single-phase alternator. The simplified version of a AC generator is discussed here.
