You've been asked to determine whether a new material your company has made is 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 o 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 Submit 1 AV Request Answer (AV)² Vertical axis AV I Not used Reset Help
