In the context of classical electrodynamics or general physics: a perfect conductor with no special quantum mechanical properties.

In classical electrodynamics, a charge moving in a circle should radiate electromagnetic radiation.

It follows from classical electrodynamics that the radiation pressure is related to the internal energy density:

According to the laws of classical electrodynamics, no current can flow through an insulating barrier.

The sign of the electric charge, field strength tensor in gauge theories and classical electrodynamics.

Note on uniqueness for a one-dimensional two-body problem of classical electrodynamics.

Furthermore, classical electrodynamics was not the only classical theory rendered incomplete.

In classical electrodynamics, problems are typically divided into two classes:

He also argues that the experiment can be understood with classical electrodynamics and has "nothing to do with quantum mechanics".

It is one of the four Maxwell's equations which is about the basis of classical electrodynamics.
