You have a capacitor and each plate is of area A, explain qualitatively what happens to the capacitance when you increase the size of only one of the plates and why.
Edit: adding some conditions:
1. they are circular discs (for simplicity's sake)
2. one has diameter d1, one has d2,
3. make d2 = 2d1, compare to capacitance when d1 = d2.
4. the separation between the two plates is negligible compared to the diameters.
this wasn't really a homework problem but it came up in my book and i don't know how to do it.
