Exam-style question
Try this first
What does the slope of a charge-potential graph represent?.
- A.Capacitance
- B.Charge stored
- C.Potential difference
- D.Energy stored
Model answer
What a good answer should say
- Capacitance
Explanation
Why this works
The slope of a charge-potential graph indicates how much charge is stored per unit of potential difference. This relationship defines capacitance, which is a measure of a capacitor's ability to store charge.
Therefore, a steeper slope signifies a higher capacitance, implying that the capacitor can store more charge for a given potential difference. Thus, the correct answer is capacitance.
