Exam-style question
Try this first
Which factor does NOT affect the capacitance of a parallel plate capacitor?.
- A.Plate area
- B.Separation distance
- C.Material of the plates
- D.Charge on the plates
Model answer
What a good answer should say
- Charge on the plates
Explanation
Why this works
Capacitance is affected by the plate area, separation distance, and the material between the plates (dielectric). The charge on the plates does not affect capacitance directly; it is a result of the capacitance and potential difference.
