Answer:

The resistivity is given as p = RA/l where p is the resistivity, R is the resistance, A is the area and l is the length. The conductivity is s = 1/p where s is the conductivity. The conductivity is therefore s = l/AR and will be measured in ohm^-1 meters^-1, also known as siemens.

Answer:

If you can assume that current is flowing uniformly across the conductor and assuming dimensions are in cm, the following equations can be used:

The voltage from point 1 and point 2 represents the voltage drop 40cm apart regardless of the space in the width dimension.

Resistance R = V/I = 14.5mv/120A = .121 mΩ

Resistivity ρ = R*A/L = .121 mΩ*(50cm *.5cm)/40cm =7.56E-5 Ω-cm (7.56E-7 Ω-M)

where A is the cross sectional area and L is the length

Conductivity σ = 1/ρ
