- - - - such as a bulb, motor or bell
  - - - don't allow eiectric currents to pass throught them
      - Wood, glass, plastic and air are insulators
    - - have properties which are intermediate between conductors and insulators
      - The most important examples are silicon and germanium
    - - Allow electric currents to pass through them
      - All metals are good conductors
  - - - Light bulb
      - Motor
      - Resistor
      - Bell
    - - Switch
      - Push button
      - Circuit switch
    - - Provide the necessary energy for electrons to circulate
    - - Fuses melt
      - Breaker switches
