Project - Analysis of a practical automotive wiring circuit

1)

battery

starter

generator

distributer

ignition coil

ammeter

fuse

foot selecter switch

current and voltage regulator

breaker

2)

breaker:-it is a electrical safety device.it protects the electrical circuit from over current,short circuit or any other fualt in the circuit.they are of diffrent type.moulded case circuit breaker(mccb),miniature circuit breaker(mcb),earth leakage circuit breaker,residual current circuit breaker and surge arrestors.

battery:-battery is the device which stores electric energy as chemical energy.it countain 2 rods named anode and cathode.

generator:-it is a machine that convert mechanical energy into electrical energy.the generated energy is either stored or distributed.mechanical energy is captured by both natural and man made resources(wind,dam..etc).

3) 

load=10A

fuse rating=125% of load

fuse rating=1.25*10=12.5A

4)

p=500w

given v=12v

l=p/v=500/12=41.6A

capacity=l*T

ASSUME LOAD 10hrs

capacity=41.6*10=416Ah

5)HORN and parking lamp.

most of the elements are connected in parallel for getting constant voltage.

6)battery and ammeter is connected in series for monitoring the current flowing through circuit.here current will be constant.
