I am studying divergence and curl in my E&M class. I was wondering, why is divergence a useful concept? I mean, for point charges, the divergence is zero everywhere except where the charge is located. Even for charged surfaces,
[tex]\nabla\cdot E = \frac{\rho}{\epsilon}[/tex]
Loooking at this it seems like you would have no divergence except on the suface. How does that help?
