How does increasing the plate area of a parallel plate capacitor affect its capacitance?.
- A.Capacitance decreases.
- B.Capacitance remains unchanged.
- C.Capacitance increases.
- D.Capacitance becomes zero.
Model answer
What a good answer should say
- Capacitance increases.
Explanation
Why this works
Increasing the plate area of a parallel plate capacitor increases its capacitance because capacitance is directly proportional to the area of the plates. A larger area allows for more charge to be stored at a given potential difference.
