Resistance Station № 3: Slide Wire Rheostats and Checking Resistivity (6/6)

The calculation to find ρ is at the bottom right of this shot. The data suggests that in our equation R=ρL/A, we were at least correct in assigning the linear dependence on L and that over the values we checked ρ does appear constant. The answer I had for the resistivity of the rheostat materal was ρ=1.39x10^-6 Ω·m
