Question

Figure shows four plates each of area A and separated from another by a distance $d$. What is the capacitance between P and Q ?\

Professor PC Thomas Classes · Answer

The figure can be represented as\  Now, the two capacitors are in parallel\ $	herefore \mathrm{C}_{	ext {eq }}=\mathrm{C}+\mathrm{C}=2 \mathrm{C}$ and $\mathrm{C}=\varepsilon_{0} \mathrm{~A} / \mathrm{d}$\ $	herefore 2 \mathrm{C}=\frac{2 \varepsilon_{0} \mathrm{~A}}{\mathrm{~d}}$\
