Electrostatics Question 548
Question: Three condensers each of capacitance $ 2F $ are put in series. The resultant capacitance is [CPMT 1976; NCERT 1981; MP PMT 2001]
Options:
A) $ 6F $
B) $ \frac{3}{2}F $
C) $ \frac{2}{3}F $
D) $ 5F $
Show Answer
Answer:
Correct Answer: C
Solution:
$ \frac{1}{C}=\frac{1}{2}+\frac{1}{2}+\frac{1}{2} $
therefore $ C=\frac{2}{3}F $
