What Is the Resistivity of Tungsten Wire?

Tungsten wire has a relatively high resistivity, which means it resists electrical current more than some other metals. Typically, the resistivity of tungsten is approximately 5.5 x 10^-8 Ω·m at room temperature. This relatively high resistivity makes tungsten wire very useful in certain applications, such as in electronic equipment and resistive heaters that operate at high temperatures. In addition, the resistivity of tungsten wire is also affected by temperature. As the temperature increases, the resistivity will also increase slightly. Therefore, tungsten wire maintains its electrical properties under high temperature conditions, which is very important for some high temperature applications.
