Consider three capacitors of capacitances C 1, C 2, and C 3 farads respectively connected in series across a d.c. supply of V volts, through a switch S w, as illustrated in Fig. 1. When the switch S w is closed, all these capacitors are charged.

The total capacitance ( C T ) of the series connected capacitors is always less than the value of the smallest capacitor in the series connection. If two capacitors of 10 µF and 5 µF are connected in the series, then the value of total capacitance will be less than 5 µF. The connection circuit is shown in the following figure.
Note that in a series network of capacitors, the equivalent capacitance is always less than the smallest individual capacitance in the network. A parallel combination of three capacitors, with one plate of each capacitor connected to one side of the circuit and the other plate connected to the other side, is illustrated in Figure 8.12 (a).

Remind them of this as an introduction but be ready to dispel any confusion that may arise because the formulae are reversed for capacitors. For capacitors in parallel the pd across each is the same. For capacitors in series, it is the charge stored that is the same. Episode 127-1: Capacitors in series and parallel formula derivations (Word, 36 KB)
