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 $
