Let $A$ be a point in space in which an electric field acts.
Let $\delta V$ be a volume element containing $A$.
The (electric) charge density $\map \rho {\mathbf r}$ at $A$ is defined as:
| \(\ds \map \rho {\mathbf r}\) | \(=\) | \(\ds \lim_{\delta V \mathop \to 0} \dfrac Q {\delta V}\) | ||||||||||||
| \(\ds \) | \(=\) | \(\ds \dfrac {\d Q} {\d V}\) |
where:
- $Q$ denotes the electric charge within $\delta V$
- $\mathbf r$ denotes the position vector of $A$.
Thus the electric charge density is the quantity of electric charge per unit volume, at any given point in that volume:
