Question

The capacitors C₁ and C₂ having plates of area A each, are connected in serieis, as shown. Compare the capacitance of this combination with the capacitor C₃ again having plates of area A each, but made up as shown in the figure.

Answer 1

Now, capacitor C₃ can be considered as made up of

two capacitors C₁ and C₂ each of plate area A and

separation d, connected in series.

Hence, the net capacitance of the combination is

equal to that of C₃
