Can someone please answer the following

The variable capacitance of an old radio tuner consists of four plates connected together. Rah plate is deprecated from its neighbor by 7 cm of air. One set of plates can move so that the area of overlap of each plate varies from 20cm^2 to 30cm^2

Are they connected in series or parallel?

In this case, we have total 7 parallel plate capacitors

They are connected in parallel because the positive terminals are connected in series and all negative terminals in parallel.

So the potential remains constant.

The minimum capacitance is

Cmin= 7e_oA₁/d=1.77*10^-12 = 1.77 pF

The maximum capacitance is

C_max= 7e_oA₂/d=2.655*10^-12 = 2.655 pF
