Electrical resistance for a given material can be a function of both area/unit thickness and material temperature. Holding temperature constant, a range of areas are tested to determine resistance. The measured resistance recorded in the table is expressed in milliohms per meter of conductor length.
(a) Plot the data on rectangular graph paper with area as the independent variable.
(b) Plot the data on log-log graph paper with area as the independent variable.
(c) Plot the data on semilog graph paper with area as the independent variable.
(d) Compute equations from these three plots using the method of selected points.
(e) Plot and find equations for parts (a), (b), and (c) using computer-assisted methods.
(f) What would be the best curve fit for this application?
