Introduction to Various Properties of Copper Wire

The resistance of a conductor is directly proportional to its length and inversely proportional to its cross-sectional area.
The conductivity is based on the resistance of a standard soft steel wire with a length of 1m and a ginger area of 1mm2 at 20 ℃, which is 1/58ohm (0.017241 ohm), and is called 100% conductivity. The greater the resistance, the lower the conductivity, and the two are inversely proportional.
Bending resistance: One end of a single thread is fixed, and the other end is added with a basket to make it vertically downward. Then, it bends back and forth 180 degrees until the velvet breaks. The more bends it makes, the stronger its bending resistance.
The maximum load or force applied to a specimen during a tensile test that causes it to fracture.
Tensile strength - the tensile breaking force per unit area that causes the specimen to fracture during a tensile test.
The elongation is within the specified standard distance, and the ratio of the increased length of the specimen after elongation to fracture to the original length is firm.
Conductors have different impedances at different temperatures, usually based on 20 ℃ or 25 ℃, with higher temperatures. The impedance will increase
