AC GENERATOR

Explain why, the direction of induced current in the coil of an A.C. Generator changes after every half revolution of the coil.

In an A.C. generator, when the plane of the armature is perpendicular to the magnetic field

If a capacitor is connected to two different A.C generators, then the value of capactive reactance is

Out of an A.C. generator and a D.C. generator : (a) which one uses a commutator (split rings) ? (b) which one uses slip rings ?

Draw phase diagram for a series LCR circuit with alternating voltage source, determine the expression for the impedance of the circuit. OR Draw a diagram of AC generator and describe it.Derive an expression for instantaneous value of induced emf .

An RC circuit as shown in the figure is driven by a AC source generating a quare wave. The output wave pattern monitored by CRO would look close to :

An AC generator consists of a coil of 200 turns and area of 5 m^(2) rotating at a constant angular speed of 60 rad /s in a uniform magnetic field of 0.05 T. The resistance of the coil is 400 omega . Calculate maximum current drawn from the generator .
