Electrostatics Question 529
Question: Three capacitors each of capacitance $ 1\mu F $ are connected in parallel. To this combination, a fourth capacitor of capacitance $ 1\mu F $ is connected in series. The resultant capacitance of the system is [MP PMT 1985]
Options:
A) $ 4\mu F $
B) $ 2\mu F $
C) $ \frac{4}{3}\mu F $
D) $ \frac{3}{4}\mu F $
Show Answer
Answer:
Correct Answer: D
Solution:
The circuit can be drawn as follows $ \Rightarrow C _{AB}=\frac{3\times 1}{3+1}=\frac{3}{4}\mu F $
