• An electric current is the flow of electrons around a circuit.
• Electricity is the presence or flow of charged particles
• Static electricity is the build up of electrons on an insulator
• Some materials do not conduct electricity – they are insulators
•  Most non-metal materials such as plastic, wood and rubber are insulators.
•  If there is a complete circuit a battery can push electrons all around the circuit. This is an electric current. 
• potential difference = how much energy has been transferred to a compound
• ammeter= measures how fast a current moves.
