D.C Motor and A.C Generator

                                            D.C Motor
An electrical device used to convert electrical energy inta mechanical energy.

Working Principle :-
Torque is produced in a current carrying coil placed in a magnetic field.

Construction: -
→Power radial magnet.
→Rectangular coil of many turns.
→Spindal.
→Copper split rings.
→Carbon brushes.
→Battery.

Carbon brushes: -
It takes the  current from battery and deliver it to coil.

Split rings:-
Are used to change the current in the faces of coil after each haif cycle. so, to rotate the coil in same direction. (means to produce torque in the same direction) .

D.C motor diagram  elaborates it well,it is given given below.

                                   A.C Generator

An device which converts mechanical energy into electrical energy.

Working Principle :-
Farady's law of magnetic induction.

Construction: -
→Power radial magnet.
→Spindal.
→Rectangular coil of many turns.
→Copper slip rings.
→Carbon brushes.
→Galvanometer.

Working: -
Its working can be studied using e.m.f vs time figure of A.C generator.

The Diagram of A.C generator is given  which will make this topic easy to understand.
