Project - Analysis of a practical automotive wiring circuit

1.

Identify each of the major elements in the above automotive wiring diagram.

1 Battery

2 Generator

3 Ammeter

4 Starter

5 Breaker

6 Distributor

2.

Explain the purpose and working of any three elements briefly.

1 BATTERY

Battery is collection of cells. It convert chemical energy into electrical energy by chemical reaction occurs in the cell of a battery. Battery provides power to start a vehicle, blow horn, start lights, wiper etc. The purpose of using battery in Electric vehical because it has high energy efficiency, high temperature performance and low self discharging. It regulates voltage. Battery store energy and exhibit when needed.

2 AMMETER

Ammeter measure current flow. Ammeter is nothing but just a flow meter. It can measure both AC and DC current. Unit of Ammeter is Amperes. It measure Charge and discharge of a battery used.

3 BREAKER

Purpose of a breaker to protect an electrical circuit from damage caused by over load or short circuit. If breaker fails it create hazard.

3.

If the total load is 10A from battery, what should be the fuse rating?

We have

Current =10A

Voltage =12V

Power =Current*Voltage

=10*12

=120 Watts

4.

If 500W is the load, what is the voltage and capacity of battery you recommend?

we have

Power =500W then Let Voltage=12V

then current would be 500/12

=41.6 A

5.

Identify any two elements which are connected parallel to each other. Why they are connected in parallel?
