I'm interested in the idea of voltage.
if the curl of E =0, then E = -grad(potential), and it's
possible to calculate the voltage between two points
as the line integral of E over some path.
When there's a time changing magnetic induction, the
curl of E = -d(B)/dt. so strictly speaking the idea of voltage
gets a little unclear.
I don't have a lot of intuition about curl and the curvature
of electric field. It seems to me that it's possible to express
an electric field in a power series of (scale_length*frequency),
but I'd like to know if there's a way to calculate the curvature of
electric field and use that to modify the idea of voltage.
I think this might have application to calculating an equivalent
circuit description of a physical device from a field solver
