Capacitance is proportional to the plate area, A, and inversely proportional to the distance between the plates, d. Figure 1: The basic capacitor consists of two conducting plates separated by a non-conducting dielectric which stores energy as polarized regions in the electric field between the two plates.

8.2: Capacitance and Capacitors
Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.

Voltage coefficient of capacitance. Ceramic capacitors exhibit changes in capacitance with variations in DC bias level. Stated differently, measuring the capacitance of a device with a 1 V P-P size wave averaging 0 V will yield a different (typically greater) value than if the same device is tested with a 1 V sine wave having a DC offset of 10 V.
