  • Resistor
    A component that is used to add resistance into a circuit
  • Resistor
    • Symbol is a zigzag line
    • Used to make a circuit dimmer by sharing potential difference with a component
  • Calculating resistance
    Divide potential difference by current
  • Ohm
    Unit of resistance
  • Higher resistance

    More energy transferred as heat
  • Increasing potential difference across resistor
    Increases current flowing through resistor
  • Ohmic conductor
    • Current is directly proportional to potential difference
    • Resistance is constant if temperature is constant
  • Resistance will only stay constant if the temperature is constant
