  1. 3. a component that can conduct current in either direction when it is triggered
  2. 4. a device that converts AC into DC
  3. 9. a device that converts DC into AC
  4. 10. the value of these can be discovered by their coloured bands
  5. 11. a semi-conductor device that uses light energy to generate electric current
  6. 13. a semi-conductor light source
Down
  1. 1. component used for switching and amplifying electronic signals
  2. 2. a type of diode that conducts in one direction when its 'break over voltage' has been reached
  3. 5. a semi-conductor that conducts when its 'gate' receives a current trigger - has three states
  4. 6. a type of diode that can pass current in both directions when the voltage is high enough
  5. 7. a type of resistor whose resistance varies with temperature - two types (PTC & NTC)
  6. 8. component that stores energy in an electric field
  7. 12. component that allows current to flow in one direction whilst blocking it in the opposite direction
