Y8 Science Electricity 💡🔋

• Circuit


  A path through which electricity flows, made up of a source of electricity, a conductor and a device that uses the electricity.
• Conductor


  A material that allows electricity to flow through it, like copper wire.
• Insulator


  A material that prevents electricity from flowing through it, like rubber or glass.
• Voltage


  The "pressure" that drives electricity through a circuit, measured in volts (V).
• Current


  The flow of electricity through a circuit, measured in amperes (A).
• Electricity


  A form of energy that flows through wires and circuits.
• Electricity can be transferred by induction when two conductors are brought close together without touching.
• When an electric current passes through a component, energy is transferred into heat, light or sound.
• Charged particles


  • Positively charged particles (e.g. protons or positive ions)
  • Negatively charged particles (e.g. electrons)
• Electric current


  The flow of electrons
• Electrical circuit


  Made up of components, connected together using wires
• Static electricity


  The build up of electrons on an insulator
• Insulator


  A material that does not allow current to flow through it easily (e.g. wood or glass)
• Conductor


  A material which allows electrical current to flow through it easily (e.g. copper or gold)
