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.

  1. 01

    Identify nodes and branches before applying any circuit equation.

  2. 02

    Use charge and energy conservation at the correct part of the network.

  3. 03

    Check polarity, current direction, units, and the behaviour of limiting component values.

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.
