Energy Density Formula
The energy density of a capacitor or electric field is represented as Jm2
Electrical Energy Density = Permittivity × (Electric Field)2 /2
UE = (1/2)ε0E2
Volumetric Energy Density
Volumetric Energy Density = Energy / Volume
Where energy is in joules (J) or watt-hours (Wh), and volume is in cubic meters (m³) or liters (L).
Gravimetric Energy Density
Gravimetric Energy Density = Energy / Mass
Where energy is in joules (J) or watt-hours (Wh), and mass is in kilograms (kg).
How to calculate Energy Density?
Energy density is a concept that describes the amount of energy stored in a given volume or mass of a substance. It is measured in units such as watt-hours per litre (Wh/L) or watt-hours per kilogram (Wh/kg). It has applications in various fields like physics, engineering, material science, etc.
There are various types of energy, such as kinetic energy, potential energy, chemical energy, electrical energy, magnetic energy, nuclear energy, thermal energy, and sound energy. The above types of energy play an important role in the understanding of energy density. They all contribute to the total energy stored in a system per unit volume or mass.
In simple words, energy density indicates the amount of energy stored in a specific volume or mass.
