Factors that affect wire resistance are as follows

1. Temperature

The effect of temperature on various materials is different. For example, the electrical resistance of copper and steel increases with temperature. For some materials, the resistance of the material decreases with temperature. When conducting wire resistance measurements, we need to disconnect the wire under test from the circuit.

2. Cross-sectional area

The larger the cross-sectional area of ​​the wire, the more electrons can pass through in the same amount of time. The thinner the wire, the harder it is for current to pass and the greater the resistance of the wire. The resistance decreases as the diameter of the wire increases. When replacing a wire harness, use a wire harness of the same wire diameter. If a thinner wire harness is used, the resistance of the wire increases, the resistance increases, the power dissipated by the wire increases, and the wire harness overheats or melts.

3. Length

As the length of the wire increases, the resistance increases because the electrons have to pass through more atoms. Electrons traveling through shorter wires encounter fewer atoms and therefore have less resistance.

4. Rust

Corrosion in the circuit also affects resistance, which increases after rusting.

Harness plugs are rarely seen in life, and are not used much in real life, but in the auto repair industry, wire harness plugs are a basic common plug-in tool, called a relay station for line transfer, which can be connected to a variety of ports , to achieve line circulation.
