AQA GCSE Combined Science Trilogy (Physics) Required Practicals for the Electricity topic

Required practical activity 15: Use circuit diagrams to set up and check appropriate circuits to investigate the factors affecting the resistance of electrical circuits. This should include:

1. the length of a wire at constant temperature
2. combinations of resistors in series and parallel.

Required practical activity 16: use circuit diagrams to construct appropriate circuits to investigate the I–V characteristics of a variety of circuit elements, including a filament lamp, a diode and a resistor at constant temperature.
