Electrostatics Question 618
Question: When two identical capacitors are in series have 3mF capacitance and when parallel 12mF. What is the capacitance of each [DPMT 2002]
Options:
A) $ 6\mu F $
B) $ 3\mu F $
C) $ 12\mu F $
D) $ 9\mu F $
Show Answer
Answer:
Correct Answer: A
Solution:
In series $ {C}’=C/n $ i.e. $ C=n{C}’=2\times 3=6\mu F $
In parallel $ {C}’=nC $ i.e. $ C=\frac{{{C}’}}{n}=\frac{12}{2}=6\mu F $
