How does current electricity move?

Answer 1

In a conductive material, the atoms have a number of electrons which freely move back and forth from atom to atom. When an electric potential is applied across the conductor, more electrons start moving in from the negative end. The extra negative charge repels the electrons that are already in the conductor, so they start moving towards the 'positive' end. Electrons are negatively charged, and like charges repel each other.

Because there are negatively charged particles (the electrons) moving from negative to positive, we conveniently say that 'current flows' from positive to negative (there are these imaginary positively charged particles), but this is just a concept which makes it easier to think about, and not actually how it works.

Answer 2

Current electricity, or electric current, moves through a conductor like a wire when a voltage is applied. The flow of electrons in the conductor creates the electric current. Essentially, it is the movement of charged particles in a continuous loop from a point of higher potential to a point of lower potential.
