Alternating current is produced by AC generator.If the frequency of rotation of electromagnet In a generator Is Increased, the voltage.

What is the working principle of AC generator?

Current is induced when the armature of a generator rotates. Slip eings and brushes are the ways and means by which this current is brought to the outer circuit. Is this arrangement necessary if the magnet in generator is made to rotate.

Which part produces magnetic field for the working of a generator ?

The orderly distribution of electromagnetic radiations according to their wavelength or frequency is called electromagnetic spectrum. Identify the constituent radiation of electromagnetic spectrum which produces greenhouse effect.

In an AC generator which part is kept stationary,Why?
