Project - Analysis of a practical automotive wiring circuit

Q1)

1.Battery

2.ignition coil

3.starter

4.generator

Q2)1.ignition coil:-The ignition coil is a component in the engine's ignition system that converts low voltage from the battery into high voltage required to create a spark at the spark plugs. This spark ignites the air-fuel mixture in the engine's combustion chambers, allowing the engine to start and run.

2.starter:-The starter is an electric motor that engages with the engine's flywheel or flexplate to initiate the engine's rotation. When the ignition switch is turned to "Start," the starter motor receives an electrical current from the battery and spins, causing the engine's crankshaft to rotate. This rotation allows the engine's pistons to create the necessary compression and suction for the combustion process to begin. Once the engine starts running, the starter disengages from the flywheel or flexplate. The starter is essential for starting the engine and getting it running.

3.Fuse: Fuses are safety devices designed to protect electrical circuits from excessive current flow and prevent damage to the wiring and components. They consist of a thin wire or metal strip that melts when the current exceeds a certain threshold, breaking the circuit and cutting off the power supply.

Q3)It determine the apropriate fuse rating to the give 10amp slightly use the higher apm fuse to protect the wiring harness other electrical components.

for example if we chosee 10A than it would be sutaible for 15A fuse.

Q4) If 500W is the load, what is the voltage and capacity of battery we recomonde the capacity of battery is 12v battery and 42.67Ah

Hence,

Battery capacity=current X Run time *Run time =1

Q5)

The parking lamp and horn are connected in parallel to ensure that they operate independently of each other. When connected in parallel, each device has its own separate path to the power source (battery), allowing them to function simultaneously. This means that activating one device, such as the parking lamp, does not affect the operation of the other device, in this case, the horn. They can both receive the necessary voltage supply and operate without interference from each other.

Q6)

1) Headlights: The headlights are often connected in series, which means that the current flows from one headlight to the other in a sequential manner. This allows both headlights to receive the same amount of current and illuminate simultaneously.

2) Brake lights: Similar to headlights, the brake lights are often connected in series. This ensures that when you press the brake pedal, the electrical current flows through each brake light, causing all of them to illuminate simultaneously.
