Electrostatics Question 572
Question: The equivalent capacitance between $ A $ and $ B $ is$ 1\mu F $ . Then the value of capacitance $ C $ is [MP PET 1994]
Options:
A) $ 1.4\mu F $
B) $ 2.5\mu F $
C) $ 3.5\mu F $
D) $ 1.2\mu F $
Show Answer
Answer:
Correct Answer: A
Solution:
Total capacitance is $ \frac{1}{1}=\frac{1}{C}+\frac{1}{(1+2.5)} $
therefore $ 1=\frac{1}{C}+\frac{1}{3.5} $
therefore $ C=\frac{3.5}{2.5}=1.4\mu F $
