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.
