Electrostatics Question 632

Question: Effective capacitance between A and B in the figure shown is (all capacitance are in mF) [KCET 2004]

Options:

A) 21 mF

B) 23 mF

C) $ \frac{3}{14}\mu F $

D) $ \frac{14}{3}\mu F $

Show Answer

Answer:

Correct Answer: D

Solution:

Given circuit is balanced Whetstone bridge. So capacitor of 2mF can be dropped from the circuit therefore $ C _{AB}=2+\frac{8}{3}=\frac{14}{3}\mu F $
