Homework Statement

Homework Equations

I am not sure exactly what this question is asking for, especially in regards to the voltage drop. How would the graph of voltage drop vs Rmax-Rmin be any different to what is already provided?

I'm not sure I can solve the whole problem but since you haven't had a better answer...

The existing graph shows Resistance vs Temperature for various voltages. The question asks you for a graph with different axis but I don't think they want voltage drop vs Rmax-Rmin. They want "voltage drop per grain boundary" vs the PTC (calculated over Rmax-Rmin).

Hi, I have this exact question, did you ever manage to solve the first part of the problem?
