1. The problem statement, all variables and given/known data I am trying to find the relevent equation to to solve the following problem, RL= leakage resistance measured across the dielectric A 100pF parallel-plate capacitor has a mica dielectric of relative permittivity [tex]\epsilon[/r]=12 and a resistivity of \rho=10^14\Omega m. I want to calaculate the leakage resistance of this capacitor. 2. Relevant equations 3. The attempt at a solution The previous question wanted to know the area and distance between the plates of the capacitor, i think that this has something to do with the answer to the question, I have solved this!! I think i have all the relevent information to have an atempt at the answer but dont know and cant find the equation, I am not sure if Resistance R = rhol/A has anything to do with it because it states resistivity is \rho = 10^14 \Omega m this has thrown me?? I cant find anything that points me in the right dierction in my books or course work.
