A parallel plate capacitor is charged and then isolated. If the separation between the plates is increased, which one of the following statement is NOT correct?

Options

  1. ACharge remains constant after it is isolated.
  2. BPotential difference across the plates decreases.
  3. CPotential difference across the plates increases.
  4. DCapacitance of capacitor decreases.

Correct answer

B. Potential difference across the plates decreases.

Step-by-step solution

After separation (d) is increased: Capacity decreases as C = ₀ ~A ~d V= Q C Potential increases as capacitance decreases. Option B is incorrect
