Project - Analysis of a practical automotive wiring circuit

Q1.

Ans The major elements in the above diagram is Generator , Starter , Battery , Distributer , Ignition coil , Current and voltage Regulator

Q2.

ans 1. Starter: - The purpose of the strater is to take power from geneator and Crankup the speed of Crank shaft for intial combustion to start

2. Battery: - Battery is the main component to start the vechile when it is ideal it supply power to Starter motor, the ignition coil, and all the other minor components . it helps the car until it gets start and then battery works as a power source for all the ligths and electronic infotainment system .

3. Generator: - Generator supply electricity to whole circut when the car is motion , it generate power from the rotaion of crankshaft and also it recharge the battery

Q3.

Ans If the total load for a circut is 10A . then we need a fuse which is more than 10A rating. say 12 A and if you go in market the next fuse aftwe 10A is 15 A. So,15A switch is recomended for it

Q4.

Ans Load= 500 w we will consider a battery of 500W/hr . but the battery capacity is in A/hr so,

we know P=V*I 500= 12*I, I=500/12, I= 41.66 A

So, We need Battery Capacity of 41 A/hr with 12v

Q5.

ans The Horn and tail light are connected in parallel. the are connected in parrallel because the need the same 12v or 48 v from battery to work efficently.

Q6.

Ans The Foot swicth and tail light are connected in series. so that when current from battery comes and stop at the foot switch and when the user press the foot switch it turns from Normally opened NO to clsoed and the tail light gets on.
