Electrostatics Question 630

Question: Three plates of common surface area A are connected as shown. The effective capacitance will be [Orissa PMT 2004]

Options:

A) ε0Ad

B) 3ε0Ad

C) 32ε0Ad

D) 2ε0Ad

Show Answer

Answer:

Correct Answer: D

Solution:

The given circuit is equivalent to parallel combination of two identical capacitors, each having capacitance C=ε0Ad .
