What is electric current on an atomic level?

Nature of electricity: the composition of atoms and how conductors work. ... To understand electricity, we need to think about the world at the atomic level. Air, water, living beings and matter are all made ... The electrons jump from one atom to the next in a domino effect which is what we call electric current. read more

Even on an “atomic level”, electrical current is still a “transfer of electrical charge”. However, your question is still a good one, in that things are not as simple as they are first explained to you, when learning about “electrical current”. The “property” of “charge” is a fundamental one. read more

drift velocity = current. voltage drop = energy used for exciting electrons over the gap. When connecting current, to a circuit, due to the voltage (potential) difference at the start to the end, electrons start to flow. read more
