the round capacitor is not hard pressed; instead it is left round (Figure 11). Then, depending on whether the Al can is oil-filled or dry-filled, the capacitor goes through a process to place the bound capacitor inside the Al shell and fill with oil or resin. The capacitor, whether resin-filled or dry-filled, must be cured before it is capped off.

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.
