The capacitance of parallel plates capacitors varies
- A. inversely as the square of the distance between the plates
- B. directly as the square of the distance between the plates
- C. inversely as the distance between the platesCorrect
- D. directly as the distance between the plates
Explanation
Capacitance C = εA/d. As the separation distance d between the plates increases, capacitance decreases — C is inversely proportional to d.
