Final answer:
Routing distribution is essential for ensuring device operation, safety, and system flexibility. It provides a complete circuit through the live and neutral wires and prevents overloads for the safe function of electrical devices, also allowing for efficient connections.
Step-by-step explanation:
Three reasons why routing distribution is necessary include ensuring electrical devices operate efficiently, maintaining safety in electrical systems, and allowing for flexibility in connecting multiple devices. When a voltage source is connected to an electrical device, two conducting paths are needed to provide a complete circuit allowing the current to flow, which is essential for the operation of the device.
First, the two conducting paths, also known as the live and neutral wires, establish a closed circuit, enabling electrons to flow from the voltage source through the device and back. This completes the electrical circuit and allows the device to function. Second, having a proper routing distribution helps prevent overloads in the electrical system, which is crucial for safety, as overloaded circuits can lead to fires. Lastly, an organized distribution of routes allows for various devices to be connected efficiently, making electrical systems in homes and businesses more manageable and adaptable to changes.
