1. The problem statement, all variables and given/known data There is a bent bar with inner radius A and outer radius B and thickness C. Bar is bent from the x axis to the y axis in a quart circle. 1) If the bottom of the bar has potential 0 and the top has potential Vo, find Resistivity. 2) If the inner circle had potential 0 and the outer circle had potential Vo, find the Resistivity. 3) If one end has potential 0 and the other has potential Vo, find Resistivity. 2. Relevant equations Ohm's Law, J = σE 3. The attempt at a solution I attempted to find the volume of the bar, which I found to be (b^2 - a^2)*c*(pi/8). I think I now need to find an electric field, but would like a bump in a correct direction.
