## Main Question or Discussion Point

Hi All,

As I understand it, a conservative field means that the energy expended by an outside agent in going between any two points is independent of the path so that the closed line integral of Edotdl is zero.

This is presented in the study of electrostatics.

It seems to me that you can have a conservative field under time varying conditions but I'm not sure!

I'm thinking about central force fields which are conservative. As an example, let's take the inverse r squared relationship and assume that the square inverse relation stays the same but the constant in the coulomb law equation increases with time.

Am I correct in saying that, this too is a conservative field?

Thank you,

Bob
