Project - Analysis of a practical automotive wiring circuit

1. a)Battery, b) current and voltage regulator, c) Generator d) Ammeter e) Breaker f) junction block. g) fuse.

2. BATTERY.

• The primary functions of battery in automotive engines are to power the starter motor so as to run the engine.
• All electrical components in a vehicle rely on the battery.
• In modern cars where most parts like the injector system, spark plug, sensors are also powered by the battery.

CURRENT & VOLTAGE REGULATOR.

The function of Regulator is to regulate the output voltage generated by the alternator so that it is stable by regulating the size of the current flowing to the rotor coil and regulating the strength of the magnetic field on the rotor coil.

GENERATOR.

The generator work is to convert Mechanical energy into Electrical energy.

• provides a constant and continuous battery charge when the engine is running;
• provides power to all systems during engine start, when the starter consumes a large amount of electricity.

3. For 10A load we can use 10 A fuse but in some small fluctuation in circuit it could be get fuse,

so we can go for 12A fuse orelse according to the noms, 1.5 * the load of battery 15 A fuse can also we use for safe.

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

assuming that for 12v battery, 500w/12v/70 % efficient =60 amps.

5. plantc light and dome lights are connecteted in parallel,

it reduces power losses and results more operation applications.

6.Battery and Ammeter are connected in series.

An Ammeter is a device used to measure the current flow through a conductor.so it can be connected in series.
