Did you know?
WebThe resistance value of a wire depends on three parameters: resistivity, length and diameter. The formula to calculate wire resistance is as follows: ... Nichrome and Constantan are often used as resistance wire. Look in the table for material … Constantan is a proprietary name for a copper–nickel alloy also known as Eureka, Advance, and Ferry. It usually consists of 55% copper and 45% nickel. Its main feature is the low thermal variation of its resistivity, which is constant over a wide range of temperatures. Other alloys with similarly low temperature coefficients are known, such as manganin (Cu [86%] / Mn [12%] / Ni [2%] ).
