The type of charge produced when electrons are removed.

The type of charge produced when electrons are gained.

Electric fields

Physics

Moving electric charge

Linking current, potential difference and resistance

Resistance of a wire at a constant temperature

Analysing series circuits

Adding components to a parallel circuit

Analysing parallel circuits

In the Circuit components unit, they will build on this knowledge to learn how the resistance of filament lamps and diodes change with current and about the properties and applications of light dependent resistors and thermistors.

In the Resistance and parallel circuits unit, pupils learnt about electrical resistance and parallel electric circuits.

This unit covers static electricity, electric fields, and current flow in series and parallel circuits. It explains current, resistance, and potential difference relationships and explores diodes, thermistors, and LDRs. The focus is on calculations, experiments, and accurate measurements.
