Contents
Outcomes
- Pupils can explain how changing resistance changes current
- Pupils can link voltage, current and resitance
Specification References
- 2.12 describe the qualitative effect of changing resistance on the circuit on the current in a circuit
- 2.15 recall and use the relationship between voltage current and reistance V=IR
Starter
Give pupils white boards ask them to draw a standard test circuit - i.e. a circuit which they can use to test any standard component (e.g. a resistor)
Pupils should include a power supply, ammeter (in series), a test component (e.g. a resistor), voltmeter (in parallel around the test component).
For bonus marks ask them to identify the positive terminal of their supply
Main Body of Lesson
- Make a 10 ohm resistor - classic
