Measuring the voltage across a capacitor

Hey guys, So this is my first project using an arduino uno and am having some trouble. The goal of the project I am doing is to try and measure the voltage across a parallel plate capacitor. The way I have it set up is like this: Digital pin 13 provides 5V to one side of my capacitor and analog pin 3 reads the voltage off the other plate. The only values I get, though,

How does a capacitor resist changes in voltage?

In other words, capacitors tend to resist changes in voltage drop. When the voltage across a capacitor is increased or decreased, the capacitor "resists" the change by drawing current from or supplying current to the source of the voltage change, in opposition to the change." capacitor; charge; field ; Share.
