An electric circuit with one complete loop, from one end of a battery round to the other end.

A component that uses a chemical reaction to make electric charge flow round a circuit.

A circuit with more than one complete loop, from one end of a battery round to the other end.

Loops of a parallel circuit

Science

about the properties of electric fields, moving electric charge, and how to analyse series and parallel electrical circuits.

In the Series circuits unit, pupils learnt about static electricity (electric charge), setting up series circuits using circuit diagrams, finding and replacing faulty components, and the rules for electric current and voltage in series circuits.
