Code to add this calci to your website  #### Formula:

Nichrome Resistance = ρl / a Where, ρ = resistivity constant of nichrome = 1.10 x 10-6 ( Ω.m ) l = length of the wire (m) a = cross sectional area of the wire (m2)

#### Example

A wire of 7 m with cross sectional area of 15 m^2, has a resistance of
= 1.10 x 10-6 x 7 / 15
= 0.5133 ohms

Nichrome is any of various alloys of nickel, chromium, and often iron. Nichrome wire is most commonly used as a resistance wire. They are also used in some dental fillings and in a few other applications. It is also known as NiCr, nickel-chrome, chrome-nickel, etc. In electric ignition systems, Nichrome wire mainly used as a bridge wire in the explosives (bombs) and fireworks industries. Measure its resistance at a known temperature, and calculate what resistance you expect at the desired temperature using this Nichrome Wire Resistance Calculator.
