Project - Analysis of a practical automotive wiring circuit

1.) Fuse, battery, current & voltage regulator, breaker.

2.) Battery: Batteries function by converting chemical energy into electrical energy and vice versa. Within a battery, chemical reactions occur between electrodes and an electrolyte. During discharge, these reactions release electrons, generating an electric current that powers connected devices. Conversely, during charging, an external power source drives the reverse reactions, storing electrical energy as chemical potential. The electrolyte facilitates ion movement between electrodes, maintaining charge balance.

Light switch: A light switch operates by interrupting or completing the flow of electrical current to control the illumination of a light fixture. It typically consists of a mechanical lever or button connected to an electrical circuit. When the switch is in the "off" position, a gap is created in the circuit, preventing current flow and keeping the light off. When the switch is toggled to the "on" position, it closes the circuit, allowing electricity to flow and powering the light fixture, thereby illuminating the area. This simple mechanism enables users to easily control the lighting in a room, providing convenience and energy efficiency.

Horn: A horn operates on the principle of converting electrical energy into sound energy to produce a loud, audible alert signal. It consists of a diaphragm, an electromagnet, and a power source. When the horn button is pressed, electrical current flows through the electromagnet, creating a magnetic field. This magnetic field attracts and repels the diaphragm, causing it to vibrate rapidly. As the diaphragm vibrates, it compresses and rarefies the surrounding air, generating sound waves. These sound waves propagate through the air as audible sound, creating the characteristic horn sound.

3.) Recommended Fuse Rating = Total Load × Safety Margin

Let's calculate it:

Recommended Fuse Rating = 10A × 1.25

Recommended Fuse Rating = 12.5A

4.) 24 V 20.83 ah battery

5.) Providing redundancy: If one element fails, the other can still function, ensuring continuity of operation.

Sharing the load: By connecting elements in parallel, the overall load is distributed among them, reducing the strain on individual components.

• Improving performance: Parallel connections can enhance the efficiency, capacity, or other characteristics of the circuit, depending on the specific application requirements.

6.)

• oltage division: The total voltage is divided among the elements, with each element experiencing a portion of the total voltage.
• Sequential operation: Elements connected in series are activated in sequence, providing a step-by-step process or controlled operation.
• Increasing voltage: By connecting elements in series, the total voltage across the circuit increases, allowing for higher voltage applications or components that require a specific voltage level.
