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 x10° -m. Calculate the surface resistivity of the nichrome film.
