Electrostatics Question 803
The capacitors, whose capacitance is 6, 6 and $ 3\mu F $ respectively, are connected in series with a 20 volt line. Find the charge on $ 3\mu F $.
Options:
A) $ 30\mu C $
B) $ 60\mu F $
C) $ 15\mu F $
D) $ 90\mu F $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] in series $ \frac{1}{C}=\frac{1}{C _{1}}+\frac{1}{C _{2}}+\frac{1}{C _{3}} $ and charge on each capacitor is same.
