Answer Details

The wires in the diagram are connected to a three-pin plug, which is a type of electrical plug used in many countries for electrical safety. The three wires are typically labeled as live, neutral, and earth. The live wire carries the electric current that powers your device. It is usually colored brown or red. The neutral wire returns the electric current back to the source after it has flowed through your device. It is usually colored blue or black. The earth wire is there for safety. In case of a fault in the device, it provides a path for the electric current to safely flow to the ground. It is usually colored green or green/yellow. So, the correct order of the wires is earth, neutral, and live.
