The resistance of a wire or rod of uniform cross section can be calculated as (resistivity) * (length) Resistance = ----- (cross section area) The resistivity of a material depends on its temperature. Most metals have lower resistance as the temperature drops. (typically +/-5% or +/-10%) at room temperature but the - resistance of the wire also has a positive temperature coefficient so coil resistance will increase as wire temperature increases or decreaseas wire temperature decreases. Useful formulas follow: Effect of Temperature on Coil Resistance: Coil resistance change over temperature :
