An earth wire, also known as a ground wire, is a safety feature in electrical systems that directs any stray electrical current away from a device or circuit and into the ground. This prevents electric shocks and helps protect both people and equipment from electrical faults. The earth wire is typically color-coded green or green with yellow stripes in many systems. It provides a safe path for electricity to flow if there is a fault, such as a short circuit, preventing potential hazards. The earth wire plays a crucial role in ensuring electrical safety in homes and buildings.
