Which wire in a plug is responsible for carrying current away from the component?

The neutral wire is responsible for carrying current away from the electrical component of a circuit. In a standard three-pin plug, the brown wire is the live wire, which brings electrical current to the component, while the earth wire provides protection by directing any stray current safely to the ground. The neutral wire, typically colored blue, completes the circuit by providing a return path to the power supply, allowing the current to flow efficiently in a closed loop. This ensures that electrical devices operate correctly and safely.
