For a capacitors are electronic the capacitance depends on the physical and geometrical proprieties of the device. It is given operationally by the ratio of the charge Q stored in the device and the voltage difference across the device ΔV.

In the experiment, our capacitor is similar to an aluminum electrolytic capacitor, except instead of using borax paste for the dielectric, we used a sheet of wax paper. Our capacitor uses the two aluminum foil squares to store positive and negative charges. The charge on the capacitor is proportional to the voltage across the capacitor.
To make the capacitor, proceed as follows: 1. From a roll of aluminum foil, cut a piece about 15 cm long. 2. Cut this piece into two equal parts as shown in figure A on the next page. Discard the shaded pieces. The goal is to make two approximately square pieces with tabs on them which look like figure B. 3 3.
