What makes up electric current at the atomic level

Each atom has a nucleus surrounded by a definite number of electrons. An electron is a particle of negative energy that revolves around the nucleus as a satellite does around the Earth. The electrons of certain materials, such as copper, aluminum and other metals, can easily leave their orbits; these materials are called conductors.

The electrons of other materials, like ceramic, cannot escape from their orbits; these are called insulators.

When we wave a magnet over a wire made of a metal such as copper, we create a movement of electrons in that wire. The electrons jump from one atom to the next in a domino effect which is what we call electric current. This is how we're able to deliver electricity to your home.
