B Is energy transferred as a wave or particle in classical physics?

[Naman Jain Kota]

I read a line in the book "Quantum physics of atoms, molecules, solids, nuclei, and particles" by resnick

The line is "in classical physics energy is either Transported by waves or by particles"

I have doubt is it correct, like we say eneegy is stored in electric field, is electric field considered as wave.

And is the statement true without any exception (classical physics)

I also would disagree with the statement. For example in a DC circuit there are no waves, but the Poynting vector shows that energy is transported through the static field.

 

[Chandra Prayaga]

Energy is certainly stored in a static electric field, but if it has to be transported, it has to be either by EM waves, or through a current carried by charged particles (electrons)

Nope. Calculate the Poynting vector for a DC circuit. There are no waves and the energy is carried by the field not the current.

I know this is late, and I might be a little off the comprehension track, but in that quotation from "Quantum physics ...etc." by Resnick, isn't the author alluding to the duality ... i.e. does an electron (functioning in the same manner as a photon of light) behave as a wave or a particle at the sub-atomic level.
