No. That is either a hypothesis or a law.

I don't know where you got that "explanation." I prefer the explanation
based on the kinetic theory of charged particles. In either case, the
theory IS the explanation. The above hypothesis is a prediction of the
theory.

How crappy science education really is!

Define for us the five terms as you believe they are used in physics:

Theory
Law
Hypothesis
Model
Explanation
