Project - Analysis of a practical automotive wiring circuit

1. Major elements

2. Three elements

Fuse - It is used to protect the wiring and electrical components from short circuits or overload. When excessive current flows through the circuit, huge amounts of heat are generated. This heat melts the fuse wire and breaks the circuit and protects it.
Voltage regulator - It is used to ensure a steady voltage supply from the generator. It controls the voltage produced from the generator to recharge the battery and also to power other electrical components. Without the voltage regulator, the input voltage will be very high for some electrical components and it leads to overload.
Generator - also known as an alternator is used to convert mechanical energy to electrical energy. This electrical energy is used to charge the battery and also to power other electrical components when the engine is running.

3. The fuse rating should always be above the total voltage of the circuit but not less. So, for a total load of 10A, we can use a 12A fuse.

4. P = 500W, Assuming time = 2hours and battery = 12V

E = P*t = 1000 W-hr

E = V*I*t

I = 1000/12*24 = 41.7 Ah

For a 500W load, a 12V battery with a capacity of 41.7 Ah can be used.

5. Parallel Connection:

Headlights/beam lights - The headlights are connected in parallel so that each light can get full voltage without any resistance and can glow brightly.
Tail stop - The tail stop lights are connected in parallel because even if one light fails, another can function.

6. Series Connection:

Ammeter and battery - The ammeter is connected in series with the battery to measure the current flow in the circuit.
Fuel gauge and Gas tank unit - The fuel gauge and the gas tank unit are connected in series so that when there is a change in the resistance value in the gas tank unit due to fuel level, the fuel gauge value changes accordingly.
