For which of the following parameter variation, the capacitance of the capacitor remains unaffected ____________?
Correct answer: D. Thickness of the plates
- A. Distance between plates
- B. Area of the plates
- C. Nature of dielectric
- D. Thickness of the plates
Explanation
For a parallel-plate capacitor, C = εA/d, so capacitance depends on plate area, separation, and dielectric permittivity. Plate thickness is not included in this relation, so changing it leaves capacitance essentially unchanged.
