**1. I was just trying to understand what divergence means so I hope someone can help me out.**

Well from what I have read if I take a vector field and use an infinitesimal region, if the vector going in is smaller than the vector going out there is positive divergence.

Does this mean if i make a circle with UNIT VECTORS there is ZERO divergence. Because `what is going in`, is the same as going out,

If they were NOT unit vectors or vector of the same magnitude then there Would be divergence? is that the correct concept?
