Graphs

• In resistors:

  • Current is directly proportional to the potential difference.

  
• In diodes:

  • Current will only flow through a diode in one direction

  
• In Filament Lamps:

  • Increasing current increases temperature at a decreasing rate

  
• Thermistor:

  • In hot conditions - the resistance of a thermistor decreases
  • In cool conditions - the resistance of a thermistor increases
