Calculates the dc Resistance of a single round wire of common conducting materials using the formula below.
The dc resistance of a conductor is calculated using the formula:-
Where ρ is the resistivity of the conductor in Ω.m
l is the Length in metres
A is the Cross-sectional area in metres
The values for ρ are from CRC Handbook of Chemistry and Physics 1st Student Edition 1998 page F-88 and are for high purity elements at 20°C.
