You've been asked to determine whether a new material your company has made ohmic and, if so, to measure its electrical conductivity. Taking a 0.50 mm x 1.0 mm x 45 mm sample, you wire the ends of the long axis to a power supply and then measure the current for several different potential differences. Your data are as follows: Voltage AV (V) Current I (A) 0.200 0.47 0.400 1.06 0.600 1.53 0.800 1.97 ▼ Part A You want to determine if the material is ohmic and its conductivity by graphing the data. Select the appropriate variables to graph on each axis that will produce a straight-line graph with a slope and intercept that will allow you to determine these properties. Sort all variables into the appropriate bins. Horizontal axis AV (AV)² Vertical axis AV Not used Reset Help

A student woants to identify the Resistivity of a conducting wire of unknown material. Resistivity is a property of a material that quantifies how strongly it conducts electric current, and it is formulated as, of p= R4 where R is the Resistance (ohms), A cross-sectional area (meters-squared) and I is the length (meters) of the wire. The student runs an experiment on a cylindrical wire of a length l of 2 centimeters and the cross- sectional area A of the wire is 6.1 centimeters-squared.
