Energy Density Electric Field

Question

Energy density in electric field is (in vacuum):

RankGuru · Accepted Answer

Energy density ($u$) is the energy stored per unit volume in a region where an electric field exists.
$u = \frac{1}{2} \epsilon_0 E^2$
- This applies to any region with an electric field, not just inside capacitors.
- Units: **Joules per cubic meter ($J/m^3$)**.
