Project - Analysis of a practical automotive wiring circuit

Ans 3:- Battery Voltage= 12 V Total Load=10A

Fuse Rating is given as

Fuse Rating I=P/V

P= VI=12*10=120

Fuse Rating= 120/10=12

Ans 4:- Load= 500W, Current= 10A

Solution:- I=P/V

V=P/I

V=500/10

V= 50 V

Assume the battery run time is 2 hours then,

the load on it is given as 500*2=1KWh

The battery capacity is given as, Battery Capactiy=1000/50

Battery Capactiy= 20Ah

Ans 1:- The major components of the above Automotive wiring system are as follows,

1. Battery
2. Current and Voltage Regulator
3. Starter
4. Distributor
5. Ignition Coil
6. Breaker

Ans 2:-

• Battery:- Battery the the major and the basic component of any automotive to operate, its the power source on which the other elements in the automotive are dependent on, its a DC source of a common voltage which supplies to the other elements
• Current and Voltage Regulator:- Current and voltage regulator is the device which avoid the breakdown or shortcircuit of any instrument by providing them their desired voltage, Instrument working on a fixed and definite voltage require this device so that excess current may not exceed in them and they can work in a safe environment
• Distributor:- Its a part of the system which supplies the current to the Instruments by dividing the current into other Sub currents so that it could reach the Instruments

Ans 5 :- Generator and Current and Voltage Regulator are connected in parallel so that the current generating from the generator should be controlled by the voltage regulator so it could be safe for the operating instruments

Ans 6 :- Battery and Starter are connected in series together so that there will be no split voltage for the starter it will only run at the voltage provided by the battery so that maximum power will be generated to switch on the automotive
