What does the area under a charge-potential graph represent?.
- A.The charge stored in the capacitor
- B.The energy stored in the capacitor
- C.The potential difference across the capacitor
- D.The capacitance of the capacitor
Model answer
What a good answer should say
- The energy stored in the capacitor
Explanation
Why this works
The area under a charge-potential graph represents the energy stored in the capacitor. This is because energy can be calculated as the integral of charge with respect to potential difference, which geometrically corresponds to the area under the curve.
