Question

Net capacitance between the point P and Q when A is the area of the plates and d is the distance between the plates-

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

Answer 1

Answer: (C)

$\frac{5A\varepsilon_{0}}{3d}$

Answer 2

Use point potential method to draw equivalent circuit.

C_eq = 5C/3 = 5/3 (Ī₀A/d)
