# A relationship between parallel plate capcatior's capacitance & it's spacing distance

In my experiment class, I measured a curve between the parallel plate capacitor's capacitance and it's spacing distance. But the result is not very similar to expectation - despite the spacing distance is obviously smaller than the capacitor's size, a curve looks like a quadratic.

• capacitance is measured by electrostatic pressure between plates.

• Have you evaluated the error in each of your measurements? And the effect on the results? – user207455 Jul 2 '19 at 7:34
