Question

Does electricity have inertia?

Answer 1

Explanation:

Electricity is the flow of electrical charges (usually electrons), and they have mass.

Therefore they have inertia. But their individual masses are quite tiny, and so is their associated inertia. There are other effects that vastly outweigh any inertial effects, such as the thermal vibrations of atoms. And quite often, the key to an electrical impulse is not the actual movement of electrons, but the propagation of an electrical field, and that has no inertia.

Hence, electricity has inertia if the masses of electrons have quite tiny.
