Contents
Outcomes
- Pupils can understand how current and voltage are related for bulbs, diodes and wires/resistors
- Pupils can produce the relevant I-V graphs for bulbs, diodes and wires/resistors
Specification References
- 2.11 describe how current varies with voltage in wires, resistors, metal filament lamps and diodes and how this can be investigated experimentally

Main Body of Lesson
Pupils to take experimental current and voltage readings for the following:
- 10 ohm resistor (they have already done this but they need to take the negative values of I and V)
- metal filament bulb
- diode
Once they have finished they need to plot I-V graphs
