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.

20 Magnetic fields sits inside A Level extension. Build the concept first, then practise selecting a model, showing working, and checking the final result.
