What is the effect of increasing the separation between the plates of a parallel plate capacitor on its capacitance?.
- A.Increases capacitance
- B.Decreases capacitance
- C.No effect on capacitance
- D.Increases voltage
Model answer
What a good answer should say
- Decreases capacitance
Explanation
Why this works
Increasing the separation between the plates of a parallel plate capacitor decreases its capacitance because capacitance is inversely proportional to the distance between the plates.
