Electricity

Electricity is a magical power which is everywhere in our lives. Electricity lights up our homes, cooks our food, powers our computers, television sets, and other electronic devices.

What is electricity?
All matter is made up of atoms, and atoms are made up of smaller particles. The three main particles making up an atom are the proton, the neutron and the electron.

Electrons spin around the center, or nucleus, of atoms, in the same way the moon spins around the earth. The nucleus is made up of neutrons and protons.

Each atom has a specific number of electrons, protons and neutrons. But no matter how many particles an atom has, the number of electrons usually needs to be the same as the number of protons. If the numbers are the same, the atom is called balanced, and it is very stable.

Electric charge


As in static electricity, an electricity will occur when unbalanced two objects get in contact. One object will have a positive charge (because it lost electrons) and one will have a negative charge (because it gained electrons). If one of the charged objects then touches a conductor, like a piece of metal, the charge will neutralize itself, causing a static shock.
