What is it?
What's electricity? Electricity is a form of energy that makes heat and light. Electricity may also be referred to as “electrical energy.”
Where does electricity begin? Electricity begins with the atom. Atoms are made up of protons, neutrons, and electrons. Electricity is created when an outside force causes the electrons to move from atom to atom. The flow of electrons is called an “electrical current.”
What causes the electrons to move? Voltage is the “outside force” that causes the electrons to move. Voltage is potential energy. Potential energy has the ability to perform work. An example of potential energy is an axe being held above a piece of wood. If the axe is allowed to drop onto a piece of wood, then the wood would split. Notice the word “if” appears. Potential energy does work ONLY if it is allowed to do so.
