Key learning points

1. A parallel circuit is a circuit with more than one complete loop, from one end of a battery to the other end.
2. A circuit is built systematically following a circuit diagram, round in one direction, starting from any point.
3. A parallel circuit is built systematically, completing each loop of the circuit in turn.
4. A circuit diagram is drawn systematically, following each loop round and completing each one in turn.
5. Wires in a circuit diagram are drawn with a ruler for clarity, with no tiny gaps that would break the circuit.

Keywords

• Series circuit - An electric circuit with one complete loop from one end of a cell or battery to the other end.

• Complete circuit - A circuit that has no gaps, allowing electricity to flow continuously around the circuit.

• Parallel circuit - An electric circuit with more than one complete loop from one end of a cell or battery to the other end.

• Circuit diagram - A simple and clear way of showing the setup and components in an electrical circuit.
