Question 1: types and construction of generators
There are mainly two kinds of generators used in the industries such as AC and DC
generators which are described below:
AC generator
Construction
The AC generator converts mechanical energy into the electric energy in the form of
alternative current. The construction of the AC generator involves the stator and rotor
where the stator is used to hold the windings of the armature and it is made by steel
alloys (Agbetuyi, et al., 2011). There are two kinds of rotors used in the AC generator
such as salient and cylindrical and the power supply is applied to the rotor winding with
the help of slip rings.

Working
The AC generator works in the fundamental working principle of electromagnetic
induction. According to the low of electromagnetic induction when a conductor moves
in the magnetic field then an electromagnetic field produced across the conductor. If the
close path is delivered to the conductor then induced electromagnetic field can cause
the current to flow in the device.
