The circuit used in daily life is mainly composed of a combination of live wire, ground wire, and zero wire. Live wire is used for electrification, and the color of the wire is generally red, which is the main power line; The zero wire is used to form a current circuit, and the color of the wire is generally blue; Ground wire, also known as lightning wire, is used to protect circuits, and the wire is generally yellow. In a group of circuits, the live wire provides voltage and current through the zero wire, forming a complete circuit to ensure the normal use of the electrical equipment.<br/... |
