A thin-film nichrome resistor in the form of a rectangle of dimensions 1mm x 5mm is deposited on to a glass substrate. Estimate the thickness of the film for the resistance measured between electrodes contacting the 1mm edges to be 1.0 k2. The resistivity of 'nichrome' may be taken to be 1.07 x100-m. Calculate the surface resistivity of the nichrome film.

Six cylindrical core plugs of 2.54 cm diameter and 3.81 cm length were taken from an Alaskan North Slope reservoir. After cleaning, porosities of all the plugs were measured by a helium porosimeter. Subsequently, all samples were fully saturated with a 0.07 Ω m brine such that Sw = 1. Each sample was placed in a resistivity apparatus, and ΔV values were measured for a current flow of 0.01 A. Determine the formation factor F, for each core plug, and estimate parameters a and m for Archie’s formation factor equation.
