Four metallic plates A, B, C and D of same size with same separations between them are arranged as shown in the figure. Dielectric slabs of dielectric constant 2 are arranged between B, C and C, D respectively. The effective capacitance between A and C is
$\mathrm{C}$
$\frac{4}{3} \mathrm{C}$
$\frac{4}{5} \mathrm{C}$
$3 \mathrm{C}$
Solution
The overall effective capacitance is $4C/3$ after considering series and parallel grouping.
