[SOLVED] Capacitance vs. Distance of separation 1. The problem statement, all variables and given/known data Hi, I am suppose to make a capacitance vs (1/d) graph. I understand that the relationship between the capacitance and distance between the plates is inversely proportional and that it does not produce a straight line. My instructor mentioned that when graphing the C vs 1/d graph it would have a negative slope, but when plotting the point in excel I get a graph with positive slope. 3. The attempt at a solution 1/d is on the x axis and C is on the y axis. Does this graph seem correct, or should I go with the graph that has the negative slope which I can only get by using a C vs d relationship.
