Two identical capacitors are joined in parallel, charged to a potential V and then separated and connected in series, i.e., negative plate of first is connected to positive plate of second :
- A the charges on the plates connected together are destroyed
- B the charges on the free plates are decreased
- C the potential difference between the free plates become 2 V
- D the potential differences between the free plates becomes 4 V
Answer & Solution
Correct Answer
(C) the potential difference between the free plates become 2 V
Step-by-step Solution
Detailed explanation
\(Q = CV\) \(V_{total} = V_1 + V_2\) \(V_{total} = V + V = 2V\)
