Project - Analysis of a practical automotive wiring circuit

ANS

1. Battery ,Ignition switch , Starter , Ignition Coil , Distributer , Breaker , Generator, Current and Voltage Regulator, Junction Block, Fuse, Light switch, Scaled Beam , Gas/Fuel Tank Unit, Horn, Parking Lamp, Beam Light, Earthing for every elements, Horn button , Stop Light.

3. Fuse rating for 10A load must be 14A to 15A , If current flows Above 15A fuse must cut off for application Saftey.

4. Battery Voltage of 24V or 48 V is enough for 500W motor.

Battery Capacity of 24Ah to 30Ah.

5. Scaled Beam , Horn , Parking Lamp, Current and Voltage regulator .

They are connected parallel because if one of the application stops working or its connection fails then other can work properly without any disturbance of other application.

6. Battery is connected in Series with starter motor,

Ignition Switch is connected in Series with Ignition Coil.

They are connected in series to keep the desired voltage of battery at the same Ah.

2. A) Generator :-

Purpose of Generator is to Convert Mechanical Energy into Electrical Energy , And to provide electricity to Grid.

Working :- Components of Generator includes Armature coil, Magnets , Brushes, Commutator ,Shafts , Bearing ,Slip rings , Frame for covering and support.

Generator works on Principle of Electromagnetic Induction. Generator is also known as Dynamo or

Alternator.

Armature Coil rotates in strong magnetics field and cuts the magnetic field and EMF is induced across the

Coil. Armature is mounted on Shaft . Bearing helps and supports the shaft to rotate in generator.

Brushes are in contact with coil used to transfer the induced EMF tothe load connected in ckt of Generator.

Slip Rings transfers power into the coil when it is in rest to move . Commutator makes sure that the

current flows in one direction. Step up transfer is used to increase the voltage in the grid or transmission

line.

B) Fuse:- Purpose of fuse is to protect Electrical Equipment From overflow / excess flow of currents in ckt.

Working:- Fuse is a saftey device which protect the Electrical Equipments.

Fuse works on the Principle of Heating Effect due to excess flow of electric current.

Metal wire is used in the fuse to transfer the current , But as the excess currents flows excess heat is

generated in the fuse wire which melts and breaks the CKT contact and saves the Electrical Equipments

Types of Fuse are Cartridge Type , Rewirable type , High Rupturing Capacity type.

C) Battery:- Purpose of battery is to stores energy in the form of chemical energy and supply energy in the form of

electric energy when it is in need.

Working :- Components of battery is Anode and cathode electrode , electrolyte , seperator.

Anode is a negative or reducing electrode , cathode is a oxidizing electrode. electr
