Exam-style question
Try this first
Which equation is used to calculate the charge stored in a capacitor?.
- A.Q = CV
- B.C = Q/V
- C.V = IR
- D.E = 1/2 CV^2
Model answer
What a good answer should say
- Q = CV
Explanation
Why this works
The equation Q = CV relates the charge (Q) stored in a capacitor to its capacitance (C) and the potential difference (V) across it, which is essential for capacitor calculations.
