Density Divergence Electric Electric field Field Flux Flux density

AI Thread Summary

Flux density is defined as the amount of electric flux passing through a unit area, while divergence measures the rate at which electric field lines spread out from a point in space. The discussion clarifies that flux density can be understood as electric field per unit area vector. Divergence is specifically defined as flux per unit volume, indicating a distinction between the two concepts. Overall, the participants agree that flux density and the divergence of the electric field are different quantities.

Homework Statement: Is flux density same as divergence of electric field

Relevant Equations: Div E = (lim as V tends to zero) of (1/V) E*dS
V is volume

I think Flux density is flux/Volume.
Or is it flux/ Area
Please be kind to help

Thanks a lot, Gordianus!

I think flux density is electric field / unit area vector...
So flux density and divergence of E are different,right?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
