What is the relationship between the charge (Q) stored in a capacitor and the potential difference (V) across it?.
- A.Q = V^2
- B.Q = C/V
- C.Q = C × V
- D.Q = V/C
Model answer
What a good answer should say
- Q = C × V
Explanation
Why this works
The relationship is defined by the formula Q = C × V, where Q is the charge stored, C is the capacitance, and V is the potential difference across the capacitor.
