A filament is a thin metal wire inside some light bulbs that glows and emits light when heated.

A faulty component is one that is damaged or isn't conducting electricity properly.

A series circuit is an electric circuit with one complete loop from one end of a battery to the other end.

A complete circuit is one where there are no gaps, so electricity is able to flow round the circuit.

A test circuit is used to check if a component (or other circuit) is allowing electricity to flow through.

In the Magnets and electromagnets unit, they will build on this knowledge to learn about how electric current flows through electromagnets, factors that affect the strength of electromagnets and uses of electromagnets that include a simple electric motor.

In Changing circuits unit (Y6), pupils learnt to construct simple circuits, and about complete circuits, circuit diagrams and how the number and voltage of cells in a battery affect components in a circuit. 

This unit covers electric current, potential difference, and resistance in series and parallel circuits. It also explores charge separation, electron transfer, and electric fields. The unit focuses on interpreting data, identifying patterns, and drawing conclusions using scientific knowledge.
