Electricity and magnetism: current, voltage (potential difference), charge, resistance; relationships between them and links to energy and power. Elementary circuits including batteries, wires, resistors, filament lamps, diodes, capacitors, light dependent resistors and thermistors; series and parallel circuits. Elementary electrostatic forces and magnetism; electromagnets, motors and generators. Current as a flow of electrons; thermionic emission and energy of accelerated electron beams.
Quite a few of the questions in the PAT involve capacitors, which you probably won’t have covered at AS level, so it is important that you learn about capacitors and especially simple RC circuits and time constants. If you are doing Further Maths you might be interested to look at some material about AC circuits and impedance, but you only really need to learn about DC to do the PAT questions.
