Designed for the Physics International Baccalaureate (IB) but can be adapted for A Level.
Learning Objectives
- Apply the equation for resistance in the form where ρ is the resistivity of the material of the resistor.
- Heating effect of current and its consequences
- Investigating one or more of the factors that affect resistance experimentally
Success Criteria
All – Take measurements from an ammeter and voltmeter to calculate resistance.
Most – Solve simple resistivity problems and plot graph.
Some – Solve complex resistivity problems and conclude the relationship between length, cross section and resistance.
