Question

Seven identical plates each of area $A$ and successive separation $d$ are arranged as shown in figures. The effective capacitance of the system between $P \,\&\, Q$ is

• A. $\frac{7 \varepsilon_{0} A}{d}$
• B. $\frac{6 \varepsilon_{0} A}{d}$
• C. $\frac{5 \varepsilon_{0} A}{d}$
• D. $\frac{3 \varepsilon_{0} A}{d}$

Answer 1

Answer: (B)

All are in parallel
$C_{\text{net}}=6 C=\frac{6 A \varepsilon_{0}}{d}$
