Question

2. Explain the construction and working
of the follwoing. Draw a neat diagram
and label it.
a Electric motor
b Electric Generator(AC)​

Answer 1

Answer:

Electric motors

• A power supply – In general, a simple motor has a DC power source. It provides power for the armature of the motor or field coils.
• Field Magnet (can be a permanent magnet or an electromagnet) – The magnetic field by virtue of Fleming’s left-hand law, helps to produce a torque on the rotating armature coil.
• An Armature or rotor – Maintains the position of the armature coil and provides mechanical support.
• Commutator – It is the Armature Coil revolving interface with a stationary circuit.
• Armature Coil – Supporting the engine to run.
• Brushes – It is a system that conducts current between stationary wires and moving parts, mostly rotating shafts.
• Axle

Electric Generator

• An AC generation is an electric generation that converts mechanical energy into electrical energy in form of alternative emf or alternating current it works as the principals of Electromagnetic Inductor working of an generator:
• When the armature rotate between the poles of the magnet an axis perpendicular to the magnetic field the flux which links with the armature changes continuously Due to this on emf is induced in the armature This produces on electric current through galvanometer & the slip rings & brushes. 

The galvanometer rings between the positive & negative values This indicates that there's is an alternating current flowing through the galvanometer.
