Year 8 Energy: Electrical Circuits Revision

Vocabulary flashcards covering Year 8 topics on series and parallel circuits, circuit measurement tools, and electrical safety.

Ammeter

An instrument connected in series that measures electric current in amperes.

Voltmeter

An instrument connected in parallel across a component that measures voltage in volts.

Current in a Series Circuit

Current travels along a single continuous path through all connected components.

Current in a Parallel Circuit

Current divides and flows through separate individual branches.

Voltage in a Series Circuit

The total supply voltage is shared among the components in the circuit.

Voltage in a Parallel Circuit

Each separate branch receives the full supply voltage.

Broken Globe in a Series Circuit

An interruption where if one globe breaks, the current's only path is broken and the remaining globes go out.

Broken Globe in a Parallel Circuit

An event where if a globe in one branch breaks, the remaining branches continue to work independently.

Safety Switch (RCD)

A protective device designed to help protect people from electric shock.

Electrical Safety Protocol

Practices that include not touching damaged cords, exposed wires, or electrical equipment with wet hands, and stopping use of damaged equipment to report it to a teacher or responsible adult.
