  • Diode
    • Only allows current to flow through it in one direction
  • Rectifier
    A component that turns an alternating current (repeatedly changes direction) into a direct current (one direction)
  • Diodes act as rectifiers
    They block the alternating current when it changes direction
  • Thermistor
    A component that resistance changes with its temperature
  • Thermistor
    • Increasing temperature usually decreases the resistance
  • LDR (Light Dependent Resistor)
    A component whose resistance changes with light intensity
  • LDR
    • Increasing light intensity usually decreases the resistance
