The type of charge produced when electrons are removed.

The type of charge produced when electrons are gained.

The type of force due to electrically charged objects.

A device that produces electric charge and is used in electrostatic experiments.

The invisible field around a charged object that causes another charged object to experience a force.

Electric fields

Physics

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.
