 This page will help you answer questions such as ...

 What is electrical energy?

 Can you store electrical energy?

 Quote some sources of electrical energy

 



Electrical energy and electrostatic energy stores

  • Electrical energy is usually the flow of electrical charge in the form of negative electrons.

  • When an electrical current flows ('electricity'), the electrons carry the energy from a higher potential energy to a lower potential energy - measured as the potential difference in volts.

  • A battery is a source of electrical energy but it is initially a store of chemical energy.

  • You can of course convert electrical energy to another energy store e.g. charging a battery to increase its chemical potential energy store.

  • Electrical energy can be converted into light with bulbs, thermal energy in heaters, or kinetic energy in electric motors.

  • Electrical energy can be stored as static electricity where electrical charge cannot move until the 'charged' material is placed in contact with an electrical conductor.

  • With electrostatic energy you are dealing with repulsion of like charges (+ <=> + and - <=> -) and the attraction of unlike charges (+ =><= -).

  • Any attraction or repulsion movement of charged objects involves a force acting through a distance, so work is done and energy is transferred.

  • See The usefulness of electricity, power and the cost of using electricity calculations

  • and Static electricity and electric fields, uses and dangers of static electricity
