Question

Five metallic plates each of area $A$ and separated from adjacent plate by a distance d as shown in figure. The capacitance of the system across $A$ and $B$ is:

• A. $\frac{A\, \in_{0}}{d}$
• B. $\frac{2 A\, \in_{0}}{d}$
• C. $\frac{3 A\, \in_{0}}{d}$
• D. $\frac{4 A \,\in_{0}}{d}$

Answer 1

Answer: (C)

$C=\frac{3 A \,\epsilon_{0}}{d}$
