Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. The resistance of a filament lamp increases as the temperature of the filament increases. (Required practical activity 4)
  2. The applications of thermistors in circuits eg a thermostat is required.
  3. Students should be able to explain the design and use of a circuit to measure the resistance of a component by measuring the current through, and potential difference across, the component
  4. The diode has a very high resistance in the reverse direction.
  5. Students should be able to explain the design and use of a circuit to measure the resistance of a component by measuring the current through, and potential difference across, the component
  6. The current through an ohmic conductor (at a constant temperature) is directly proportional to the potential difference across the resistor. This means that the resistance remains constant as the current changes. (Required practical activity 4)
  7. Students should be able to explain the design and use of a circuit to measure the resistance of a component by measuring the current through, and potential difference across, the component
  8. The resistance of components such as lamps, diodes, thermistors and LDRs is not constant; it changes with the current through the component. (Required practical activity 4)
  9. The current through a diode flows in one direction only.
  10. The applications of thermistors in circuits eg a thermostat is required.
  11. The resistance of an LDR decreases as light intensity increases. (Investigation)
  12. The application of LDRs in circuits eg switching lights on when it gets dark is required.
  13. Students should be able to explain the design and use of a circuit to measure the resistance of a component by measuring the current through, and potential difference across, the component
  14. The resistance of a thermistor decreases as the temperature increases. (Investigation)
  15. [The resistance of a semicondutor decreases as energy increases as more charge carriers become freed]

AFL/Key Questions:
  1. What happens to the resistance of a filament lamp as the temperature increases?
    The resistance of a filament lamp increases as the temperature of the filament increases.
  2. A diode will have a very high resistance in which direction?
    A diode has a very high resistance in the reverse direction.
  3. How does the current through an ohmic conductor (at a constant temperature) behave in relation to the current?
    The current through an ohmic conductor (at a constant temperature) is directly proportional to the potential difference across the resistor. This means that the resistance remains constant as the current changes.
  4. How could you draw a circuit to measure the resistance of a component by measuring the current through, and potential difference across, the component? (include the equation)
    A circuit which has a battery/cell with straight lines drawn between components, a component (bulb) with an ammeter in series and a voltmeter parallel to the component (bulb) ensuring all lines do not go throug the components. Using V = I R calculate the resistance by dividing potential difference by the current.
  5. How does the resistance of a diode behave in relation to the current of the component?
    The resistance of a diode changes with the current through the component in one direction and not allow current to flow in the other direction.
  6. How does the current through a diode behave?
    The current through a diode flows in one direction only.
  7. How are thermistors used for? Give an example.
    Thermistors are used in circuits to detect temperature changes, an example is a thermostat.
  8. What happens to the resistance of an LDR as light intensity increases?
    The resistance of an LDR decreases as light intensity increases.
  9. How are LDRs used in circuits? Oive an example.
    LDRs are used in circuits to detect light levels, an example is a security light.
  10. What happens to the resistance of a thermistor as the temperature increases?
    The resistance of a thermistor decreases as the temperature increases.
  11. Why would the resistance of a semiconductor decrease?
    The resistance of a semicondutor will decrease as the energy increases due to more charge carriers become freed.
