Question 650: Electrostats & 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

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