Required Practical - Resistance of components
Keywords:
  • LDR: Light Dependent Resistor (1)
  • Filament lamp: he filament lamp is a common type of light bulb. It contains a thin coil of wire called the filament. This heats up when an electric current passes through it (1)
  • Diode: A resistor allowing current to flow in one direction only. (1)
  • Thermistor: A resistor that is sensitve to temperature changes. (1)
  • Variable resistor: A resistor that can vary the flow of current in a circuit. (1)
  • Diode: A resistor allowing current to flow in one direction only. (1)
  • Resistor: a device having resistance to the passage of an electric current. (1)
  • Current (1)
  • Potential difference (1)
  • voltmeter (1)
  • Linear relationship: A relationship that is directly proportional (1)
  • Resistance: (1)

The greater the resistance of the component the smaller the current for a given potential difference (pd) across the component. How would a high resistance of a component affect the current and potential difference across the component?
Students should be able to use graphs to explore whether circuit elements are linear or non-linear and relate the curves produced to their function and properties. How could you use a graph to identify if a circuit was linear or non-linear and relate the curves to their function and properties?

Drawing graphs that identify linear and non linear relationships.
