Project - Analysis of a practical automotive wiring circuit

Ans 1)

majaor element of above automotive wiring is battery, generator, ammeter, current and voltage regulator, junction block, all switches, fuel tank, distributor, starter, ignition coil, Fuse & breaker.

Ans 2)

1.Battery:- An automotive battery is a rechargable that is used to start the motor vehicle, When insert the key in your car's ignition and turn the switch or push the button to 'ON,' a signal is sent to the car's battery. Upon receiving this signal, the car battery converts chemical energy into electrical energy. This electrical power is delivered to the generator.

Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the ignition of the internal combustion engine that actually propels the vehicle.

2.Generator:- An electric generator of motor vehicle is important to recharge the battery and power the electric system when engine is running, alternator as used as electric generator in modern automobiles,

Its main purpose of the generator is used for starting and for running the vehicle. The generator generates electrical energy. Then this electrical energy is converted into mechanical energy.

3. Ignition coil:- ignition coil as used to ignite the spark to IC engine chamber for combustion through spark plug and it transfer the current higher than current from 12V battery.

its main purpose is spark the fuel to combustion after start the engine by starter motor and this coil as higher the current level to make the spark through spark plug.

Ans 3)

Given

current I = 10 A

Fuse ratting = 1.5 * total load from battery

= 1.5 * 10

= 15A

Ans 4)

Given Power = 500W

to find voltage & battery capacity

power = V*I

500=V*10

Voltage (V) = 500/10 = 50V

Battery capacity = current *time

= 10*3 ( let considered duration of battery discharge is 3hour)

= 30Ah

Ans 5)

Element which are connected parallel

Horn

parking lamp

sealed beam

the electric current goes the both side of the horn & parking lamp each only once, the horn sound and light glow at a time without twice the resistance.

Ans 6)

Element which are connected series

Ammeter

stop light switch

dome light switch

ammeter as connected series to addres the total current passes and to identify power loss

stop and dome light seitches are connected in series because the are on / off the circuit.
