Question

In the given circuit if each plate surface area is $A$ and plate seperation is $d$. Choose the correct option(s).

• A. Equivalent capacitance of system is $\frac{2{ϵ}_{o}A}{d}$
• B. Energy stored between plates $1$ and $2$ is $\frac{{ϵ}_{o}A{\text{E}}^2}{2d}$
• C. Energy stored between plates $3$ and $4$ is zero
• D. Equivalent capacitance of system is $\frac{5{ϵ}_{o}A}{4d}$

Answer 1

Answer: (A), (B), (C)

Energy stored between plates $3$ and $4$ is zero



$C_2,C_{3}and{C}_4$ are short circuited.
$C_1=C_2=C_3=C_4=C_5=\frac{{ϵ}_{o}A}{d}$
