Project - Analysis of a practical automotive wiring circuit

1.battery,starter motor,generator,current and voltage ragulator,breaker,fuse,ignition coil,junction block,ammeter,foot selector switch

2.battery-It can use to feed the power to the whole vehicle electrical system this is the heart of the vehicle electrical system.starter-it can helps to start or crank the engine with the electrical power.fuse-it is fixed at inbetween the battery and electrical equipments and its use to prevent the electrical equipments for high electrical curent and any short circuit and what amount of current need to the system or equipment it can allows current level.

3.load current 10A, fuse can higher than the load current,so we have the market 5A,10A,15A,20A etc.. so the next level of 10A is 15A, so we take 15A fuse must

4.P=500W,V=12V,Cp=?.

P=VI, I=P/V,I=500/12,I=41.6A,Capacity of batteryCp=Ih,Cp=41.6*1=41.6Ah

Cp=41.6Ah, It will supply 41.6Amps current regularly for an hour

5. Parking lamp and dome light,it can both parellel to each because the voltage will need to same the both lights for its working effectively.

6.Battery to ammeter to fuse in serieds connection, because it will needs same current level to the next level of equipments so its in series connection the current will be in same amount .
