Project - Analysis of a practical automotive wiring circuit

1) Major elements are as mentioned below :-

° Battery ° Generator ° Ammeter ° Breaker ° Fuse ° Starter ° Current and Voltage regulator.

2) Battery, Generator, Fuse 

Battery :- An electric battery is a source of power consisting of one or more electrochemical cells with external connection for powering electrical devices.

A battery is a device that stores Chemical energy and converts it to electrical energy.

Generator :- A machine that converts mechanical energy to electricity for transmission and distribution of over power lines to domestic commercial and industrial customer.

the function of the generator is to supply current for the operation of the ignition system, the lighting system, and all other electrical parts when the engine is running and to replenish the battery after it has supplied current for starting and other purpose when engine is at rest.

FUSE :- An electrical fuse is a safety device that operates to provide protection against the overflow of current in an electrial circuit .

3) Total load - 10A

Normal car voltage :- 12 v 

:- P =VxI = 12x10 

:- P = 120 W 

Now, Fuse rating :- P/V 

Fuse rating = 120/10 = 12 Amp.

4) load = 500 Watt  

# I = 10Amp

Normal  voltage = 12v

P = 500W

:- P = VxI 

:- V = P/I 

:- V = 500/10 = 50 V 

:- Ah = Current and discharge

:- Ah 10 x 1 hr = 10 Ah 

Voltage and capacity for battery are 50V and 10 Ah
