What is the formula for calculating the energy stored in a capacitor?.
- A.E = 0.5 x Q x V
- B.E = Q x V
- C.E = C x V^2
- D.E = 0.5 x C x V^2
Model answer
What a good answer should say
- E = 0.5 x C x V^2
Explanation
Why this works
The correct formula for the energy stored in a capacitor is E = 0.5 x C x V^2, where E is the energy, C is the capacitance, and V is the potential difference. This relationship shows how energy is stored based on the capacitance and voltage applied.
