[Animation] On the atomic level electrons circle the nucleolus in cloud like manner. Sometimes electrons are able to escape the cloud. When this occurs the atom that was neutral, now becomes positive. Being positive it attracts electrons from other atoms. The chain of losing electrons and gaining electron is what an electrical current is.

The small scale is important to understand, but the large scale is what matters. Don't lose site that any where there is an electrical current created, there is a loss and gain of electrons.
