i actually do need to find the resistance, and not the resistivity. since that is just 1/σ. the geometry tsny is using is perfect, but a quarter circle instead of a full circle. isn't it just
I = (σA/L)* V
then R = L/σA?
would the strength of Vo matter to the problem? I get that it just...
Homework Statement
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...
