Electrical Energy

Energy is the ability to do work when energy is provided to an object. Everyone needs and uses energy every day, and energy is available in all forms. Electrical energy is stored in charged particles within an electric field. The electric field is just the area around the charged particles. In other words, the charged particles form powerful electric fields in other charged particles within the field. An electric field uses energy from charged particles, causing it to move - in other words, to perform a function.
