Exam points
- Define and calculate resistance with R=V/I from component, variable-resistor or graph readings, including comparisons at a stated current.
- Read resistance from a non-linear V–I graph and explain how temperature or circuit conditions change the resistance of a component.
- Use R=ρL/A and charge-carrier evidence to calculate conductor resistance or distinguish conducting and insulating materials.
- Use ideal ammeter/voltmeter resistance and circuit changes to determine current, p.d. or an unknown resistance.
