JEE Mains · Physics · STD 12 - 2. Electric potential and capacitance
Two equal capacitors are first connected in series and then in parallel. The ratio of the equivalent capacities in the two cases will be
- A \(4: 1\)
- B \(2: 1\)
- C \(1: 4\)
- D \(1: 2\)
Answer & Solution
Correct Answer
(C) \(1: 4\)
Step-by-step Solution
Detailed explanation
For series combination \(C _{ eq _{2}}= C + C \Rightarrow C _{ eq _{2}}=2 C\) \(\Rightarrow \frac{ C _{ eq _{1}}}{ C _{ eq _{2}}}=\frac{( C / 2)}{2 C }=\frac{1}{4}=1: 4\)
