What effect does increasing the separation between the plates of a capacitor have on its capacitance?.
- A.Capacitance increases
- B.Capacitance decreases
- C.Capacitance remains the same
- D.Capacitance becomes infinite
Model answer
What a good answer should say
- Capacitance decreases
Explanation
Why this works
Increasing the separation between the plates reduces the capacitance because it decreases the ability to store charge at a given potential difference.
