Domestic uses and safety key terms

earth wire

earth wire is a curriculum-aligned term linked to the learning objective: State that the earth wire is at 0 V and carries current only if there is a fault..

earth wire carries

In Mains electricity, earth wire carries means the precise GCSE Physics idea needed to state that the earth wire is at 0 V and carries current only if there is a fault. It helps avoid mixing up current, charge and time.

live wire

live wire is a curriculum-aligned term linked to the learning objective: Explain why a live wire may be dangerous even when a switch in the mains circuit is open..

live wire dangerous

In Mains electricity, live wire dangerous means the precise GCSE Physics idea needed to explain why a live wire may be dangerous even when a switch in the mains circuit is open. It helps avoid mixing up mains electricity and safety.

live wire

live wire is a curriculum-aligned term linked to the learning objective: Explain the danger of creating any connection between the live wire and earth..

danger creating connection

In Mains electricity, danger creating connection means the precise GCSE Physics idea needed to explain the danger of creating any connection between the live wire and earth. It helps avoid mixing up resistance changes with component identity.

safety

safety is a curriculum-aligned term linked to the learning objective: Apply WS 1.5 by recognising safety implications of mains electricity..

recognising safety implications

In Mains electricity, recognising safety implications means the precise GCSE Physics idea needed to apply WS 1.5 by recognising safety implications of mains electricity. It helps avoid mixing up mains electricity and safety.
