Question

In the given figure, if each plate has area A and separation between plates is d, then equivalent capacitance between A & B is

• A. $\frac{2}{5}\frac{{\epsilon }_{0}A}{d}$
• B. $\frac{5}{2}\frac{{\epsilon }_{0}A}{d}$
• C. $\frac{3}{2}\frac{{\epsilon }_{0}A}{d}$
• D. $\frac{{\epsilon }_{0}A}{d}$

Answer 1

The correct option is A $\frac{2}{5}\frac{{\epsilon }_{0}A}{d}$


$C_{eq}=\frac{2}{5}C=\frac{2}{5}\frac{{\epsilon }_{0}A}{d}$
