No, it is not for a standard E&M class, but for a scientific project. The problem is that I would like to determine the area of the bottom capacitor plate once the capacitance is measured. So, in fact, I know the area of the top capacitor plate, the distance (t) of the air gap and the total...

Thanks for your reply tonyh, but I doubt if I can simply use the smaller area. On the contrary, in some scientific papers they use the larger area instead of the smaller. But I can't find a proper reason for choosing any of the two. Do you have any reference theory to support your suggestion?

Does anyone know how to calculate the capacitance of two circular plates having different dimensions? Say the top capacitor plate has a diameter d1 and the bottom capacitor plate has a larger diameter d2 and air is in between the bottom and top plate. So, it is not a standard parallel plate...
