resistance formula

electric resistivity = 1.7×10^-8 Omega m (ohm meters)

length = 20 meters

area = 0.02 m^2 (square meters)

electric resistance

17 muOmega (microohms) = 0.017 mOmega (milliohms) = 1.7×10^-5 Omega (ohms)

R = (L ρ)/A

R = electric resistance

ρ = electric resistivity

L = length

A = area
