To understand electricity, we need to think about the world at the atomic level. Air, water, living beings and matter are all made up of tiny atoms. To give you a sense of dimension, the width of a single hair is equal to over a million atoms side by side!
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.
