Power density
Power density, defined as the amount of power (the time rate of energy transfer) per unit volume, is a critical parameter used across a spectrum of scientific and engineering disciplines. This metric, typically denoted in watts per cubic meter (W/m ), serves as a fundamental measure for evaluating the efficacy and capability of various devices, systems, and materials based on their spatial energy distribution.

8.4: Energy Stored in a Capacitor
The space between its plates has a volume Ad, and it is filled with a uniform electrostatic field E. The total energy (U_C) of the capacitor is contained within this space. The energy density (u_E) in this space is simply (U_C) divided by the volume Ad. If we know the energy density, the energy can be found as (U_C = u_E(Ad)).
