# Geometrical effects in the resistance of metals: Part 2.

One can find the equation R=(rho x L)/A, the resistance of a wire (where rho=the resistivity of the metal, L=length of the resistor, A=cross sectional area of the resistor), in any physics textbook. My presentation examines using this equation to determine the resistivity of a conical resistor (i.e. a resister in the shape of a hollow cone) instead of a linear resistor. The method involves summing an interesting series. We also have applied it to the resistance of a rectangular resistor where we compared theory to experimental results.Dodd, S., G. White, M. Kimball.
