Wire wound resistors are a type of precision resistor in which resistance is provided by a metal wire wound around an insulating core. The wire material must have high resistivity and stability over a wide range of temperatures.
Calculation
The most commonly used material for winding in wire wound resistors is a nickel-chromium alloy (such as Nichrome). This alloy offers high electrical resistance, good thermal stability, corrosion resistance, and mechanical strength, making it ideal for resistor applications.
Other materials like carbon are used in carbon composition resistors, while chromium cobalt and pure nickel are not commonly used for wire wound resistor windings.
