The ground wire in a car is the negative terminal of the battery connected to the car body, so the entire car is electrified. Electrical devices are installed on the car body, with one end connected to the positive terminal, and the negative terminal is conducted through the car body. The ground wire (negative) is the part connected to the car body. Here is more information: 1. The ground wire in a car refers to a current return line. The power comes out from the positive terminal of the battery, passes through various switches and electrical actuators, and then returns to the negative terminal of the battery through a return wire, forming a cycle that enables the electrical devices to perform various actions and functions. Cars use a single-wire system, meaning most wires carry their own power. 2. The return wires of various electrical actuators do not go directly to the negative terminal of the battery but indirectly return to the negative terminal through the car's own metal body. Any wire connected to the car's metal body can be collectively referred to as a ground wire.
