A capacitor of capacitance \(C_1\) is charged upto \(V\) volt and then connected to an uncharged capacitor of capacity \(C_2\). The final potential difference across each will be :

  1. A \(\frac{V}{\left(C_1+C_2\right)}\)
  2. B V
  3. C \(\frac{C_1 V}{\left(C_1+C_2\right)}\)
  4. D \(\frac{V}{2}\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(\frac{C_1 V}{\left(C_1+C_2\right)}\)

Step-by-step Solution

Detailed explanation

Initial charge on \(C_1\): \(Q = C_1 V\) Final potential difference: \(V_{final} = \frac{Q}{C_1 + C_2} = \frac{C_1 V}{C_1 + C_2}\)
