NEET 2021 Physics Energy Stored in Capacitors MCQ Question
Type: MCQ-conceptual-Medium-Class 12
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 the area of each plate is 'A', the energy stored in the capacitor is : (ε₀ = permittivity of free space)
A
1/2 ε₀ E²
B
ε₀ EAd
C
1/2 ε₀ E² Ad
D
E² Ad / ε₀
Correct Answer
Option C
Detailed Explanation
The energy stored in a capacitor is given by the formula U = 1/2 ε₀ E² Ad, where E is the electric field, A is the area, and d is the distance between the plates.
