Gauss’s Law in Differential Form and Cartesian Coordinates
Gauss’s Law in Differential Form In differential form, Gauss’s Law is $ \vec{\nabla} \cdot \vec{E} = \frac{\rho}{\epsilon_0 \epsilon_r} $ The next part of this post attempts to demystify this law a bit. Description of Symbols The $\vec{\nabla}$ on the left is called ‘del’, and it can be written in terms of Cartesian unit vectors and…
