Physical Law
- $\nabla \cdot \mathbf D = \rho$
where:
- $\nabla \cdot \mathbf D$ denotes the divergence of the electric displacement field $\mathbf D$
- $\mathbf D = \varepsilon_0 \mathbf E$ denotes the electric displacement field
- $\rho$ denotes electric charge density
- $\mathbf E$ denotes the electric field $\mathbf E$
- $\varepsilon_0$ denotes the vacuum permittivity.
Also presented as
Gauss's law can also be seen presented as:
- $\nabla \cdot \mathbf E = \dfrac \rho {\varepsilon_0}$
where:
- $\nabla \cdot \mathbf E$ denotes the divergence of the electric field $\mathbf E$
- $\rho$ denotes electric charge density
- $\varepsilon_0$ denotes the vacuum permittivity.
