Electrostatics Question 590
Question: The equivalent capacitance between A and B is [RPMT 1999]
Options:
A) 2$ \mu F $
B) 3$ \mu F $
C) 5$ \mu F $
D) 0.5$ \mu F $
Show Answer
Answer:
Correct Answer: D
Solution:
$ \frac{1}{C}=\frac{1}{2}+\frac{1}{1}+\frac{1}{2}=\frac{1+2+1}{2}=\frac{4}{2}=2 $ therefore $ C _{AB}=0.5\mu F $
