Question 625: Electrostatics & Capacitance

Question

A parallel plate capacitor has a uniform electric field $\overrightarrow 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 : ($\varepsilon $
0
= permittivity of free space)

Accepted Answer

Energy = Energy density $	imes$ volume
= ${1 \over 2}{\varepsilon _0}{E^2}Ad$

Answer

${{{E^2}Ad} \over {{\varepsilon _0}}}$

Answer

${1 \over 2}{\varepsilon _0}{E^2}$

Answer

${\varepsilon _0}EAd$

Answer

${1 \over 2}{\varepsilon _0}{E^2}Ad$
