yes we need to learn.
sam5710:
should we learn in detail
But in some schools it was not taught
oh...
oh...
Did ur teachers teach u this portion
yes but in short
remember the block diagram and main parts with functions
ok thanks
Thanks

Yes..Electric motor:
Working -when a current is allowed to flow through a point P Q R S the coil is starts rotating anticlockwise this happens because a downward force acts on length RS and at the same time and upward force acts on length PQ as a result the Coil rotates anticlockwise when the coil completes I have protation the position of PQ and Rs interchange the half ring Di comes in contact with brush a and half ring she comes in contact with brush be there for the direction of current in the coil pqrs get rewards know the current flows through the coil in the direction as rqp the direction of current through the coil reverse after every half rotation as a result the coil rotates in the same direction split rings helps to reverse the direction of current in the circuit called commutator.
Function-
in an electric motor the motor the split ring act as a commutator the reversal of current also rewards is the direction of force acting on the arms of the coil at this stage stage the commutator vs the direction of current and ensures the flow of current in the same direction so the motor continues to rotate the coil.
