MCQ
A parallel plate capacitor has a uniform electric field $\overrightarrow{ E }$ in the space between the plates. If the distance between plates is $'d\ '$ and the area of each plate is $'A\ ',$ the energy stored in the capacitor is$......$ $(ε_0 =$ permittivity of free space$)$
  • A
    $\frac{1}{2} \frac{\varepsilon_0 E^2 A}{d}$
  • B
    $\frac{1}{2} \frac{\varepsilon_0 A d}{E^2}$
  • C
    $\frac{1}{2} \frac{\varepsilon_0 E A}{d}$
  • $\frac{1}{2} \varepsilon_0 E^2 A d$

Answer

Correct option: D.
$\frac{1}{2} \varepsilon_0 E^2 A d$
$\frac{1}{2} \varepsilon_0 E^2 A d$
