Exam-style question
Try this first
Which equation represents the relationship between charge (Q), capacitance (C), and potential difference (V)?.
- A.Q = C × V
- B.V = C × Q
- C.C = Q / V
- D.Q = V / C
Model answer
What a good answer should say
- Q = C × V
Explanation
Why this works
The equation Q = C × V defines the relationship between charge, capacitance, and potential difference. This equation is fundamental in capacitor calculations, allowing us to determine how much charge a capacitor can store at a given voltage.
The key difference here is that this equation specifically shows how charge is directly proportional to both capacitance and voltage, unlike the other options which misrepresent this relationship.
