My question is simple; yet, I can not find the answer. In the picture below, all variables are identical; the plate separations, surface area, etc. The only difference is the fact that example 1 has 2 different dielectrics. Better yet, it has a dielectric that doesn't extend the entire distance between the two conductors. 1.Does example 1 and 2 have the same capacitance? My understanding: conventional physics explains that the dielectric opposes the electric field. With that in mind, both should have the same capacitance. 2. Does that mean the dielectric is actually creating an electric field that permeates another dielectric? This being air in example 1. 3. If air has a dielectric strength slightly higher than vacuum, shouldn't it oppose the field from conductor 1 and the field from the high k dielectric? This would mean example 1 has a higher capacitance, correct?
