(II) Three conducting plates, each of area A, are connected
as shown in Fig. 24-23. (a) Are the two capacitors thus
formed connected in series or in parallel? (b) Determine
C as a function of d1, d2, and A. Assume dā + d2 is much
less than the dimensions of the plates. (c) The middle plate
can be moved (changing the values of dā and d2), so as to
vary the capacitance. What are the minimum and maximum
values of the net capacitance?

three plates connected as shown in Fig. 24-24.
