Energy and Change:
Electricity

Electrical energy is a form of potential energy associated with electrically charged particles in atoms, molecules and ions.

Electrical energy can be:

• stored in batteries as chemical energy
  
• transferred through metal wires or by electric sparks such as lightning and
  
• transformed into other energy such as light, themal energy, sound and movement through simple electrical circuits.

Facts about electrical circuits
Electricity will only flow if there is a complete circuit

Facts about electrical circuits continued
The wires must be held on the side and the bottom of a globe to get it to light up. There are three reasons for electric circuits not working:

• an incomplete circuit
  
• a short circuit
  
• or a flat battery

A short circuit is when the electricity passes along a shorter route than the one intended.
A flat battery occurs when no more stored chemical energy is available in the battery.
