How does the separation distance between the plates of a capacitor affect its capacitance?.
- A.Capacitance increases with increased separation
- B.Capacitance decreases with increased separation
- C.Capacitance remains unchanged
- D.Capacitance becomes negative
Model answer
What a good answer should say
- Capacitance decreases with increased separation
Explanation
Why this works
The capacitance of a parallel plate capacitor decreases as the separation distance between the plates increases. This is because capacitance is inversely proportional to the distance between the plates, affecting the capacitor's ability to store charge.
