Draw the diagram of a switch which enables a parallel connection of a capacitor battery to be changed to a series one and vice versa.

Explanation

A possible circuit diagram is shown in Fig. 24.12 for the case of a five-capacitor system. It follows from the diagram that a tenposition switch is required. When the knob is in the upper position,

the capacitors are connected in parallel: when the knob is in the lower position, they are connected in series.
