STANDARD Physics Capacitance MCQ Question
A parallel plate capacitor has a uniform electric field E in the space between the plates. If the distance between the plates is d and area of each plate is A, the energy stored in the capacitor is
1/2 ε₀E²
E²Ad/ε₀
1/2 ε₀E²Ad
0E²Ad
Correct Answer
Detailed Explanation
The energy stored in a parallel plate capacitor is given by U = 1/2 ε₀E²Ad. This is derived from the capacitance formula C = ε₀A/d and the potential difference V = Ed.
