Where this fits

9 Electricity

Curriculum: Cambridge International AS & A Level Physics
Theme or group: AS Level foundations
Current framework: Examinations in 2025–2027 · Version 1

Charge, current, p.d. and power, resistance and resistivity, and I–V characteristics are in Chapter 22; non-ohmic components are in Chapter 23.

Mastery checklist

Know what success looks like.

01
Name both axes, units, and the physical meaning of the plotted quantities.
02
Connect gradient, area, intercepts, and shape to the governing physics.
03
Move between a graph, a verbal description, and an equation without changing the model.

Exam lens

Build, apply, check.

9 Electricity sits inside AS Level foundations. Build the concept first, then practise selecting a model, showing working, and checking the final result.
