Physics - Electrostatics Question with Solution | TestHub

Plate$1$is connected to plate$3$and plate$2$is connected to plate$4$. Thus, there are three capacitors in parallel, each of capacitance

$C=\frac{{\epsilon }_{0}A}{d}$



The equivalent capacitance, as shown in the figure, is

$C^{\prime }=3C=\frac{3{\epsilon }_{0}A}{d}$
