When two identical capacitors are charged individually to different po...
Explanation:
When two identical capacitors are charged individually to different potentials and connected parallel to each other, the following things happen:
Net Charge on Connected Plates:
- The net charge on connected plates equals the sum of initial charges.
- This is because, when the capacitors are connected in parallel, the charge flows from the higher potential plate to the lower potential plate until the potentials become equal.
- Since the two capacitors are identical, the charges on their plates will be equal after they are connected in parallel.
- Therefore, the net charge on the connected plates will be the sum of the initial charges.
Net Potential Difference Across Capacitors:
- The net potential difference across the capacitors is different from the sum of the individual initial potential differences.
- This is because, when the capacitors are connected in parallel, the potential difference across each capacitor becomes equal.
- The potential difference across each capacitor is given by Q/C, where Q is the charge on the capacitor and C is the capacitance of the capacitor.
- Since the charges on the plates of the capacitors are equal after they are connected in parallel, the potential difference across each capacitor will be the same.
- Therefore, the net potential difference across the capacitors will be less than the sum of the individual initial potential differences.
Net Energy Stored in Capacitors:
- The net energy stored in the two capacitors is less than the sum of the initial individual energies.
- This is because, when the capacitors are connected in parallel, the energy stored in each capacitor is given by (1/2)CV^2, where V is the potential difference across the capacitor.
- Since the potential difference across each capacitor is less than the initial potential difference, the energy stored in each capacitor after they are connected in parallel will be less than the initial energy.
- Therefore, the net energy stored in the two capacitors will be less than the sum of the initial individual energies.
Therefore, the correct options are B, C, and D.

Option a is weong because charge can neither be created or destroyed
option b is correct because the net charge of connected plates equals the sum of initial charges from law of conservation of charge
option C is correct because the net potential difference across them is different from the sum of the individual initial potential difference due to the capacitors are connected parallel in parallel connection the potential difference is constan
option b is correct because the net charge of connected plates equals the sum of initial charges from law of conservation of charge
option C is correct because the net potential difference across them is different from the sum of the individual initial potential difference due to the capacitors are connected parallel in parallel connection the potential difference is constan
