Energy transfers key terms

current

current is a curriculum-aligned term linked to the learning objective: Explain why reducing current in transmission cables reduces unwanted energy transfers..

reducing current transmission

In The National Grid, reducing current transmission means the precise GCSE Physics idea needed to explain why reducing current in transmission cables reduces unwanted energy transfers. It helps avoid mixing up current, charge and time.

National Grid

National Grid is a curriculum-aligned term linked to the learning objective: Explain why the National Grid is an efficient way to transfer electrical energy..

national grid efficient

In The National Grid, national grid efficient means the precise GCSE Physics idea needed to explain why the National Grid is an efficient way to transfer electrical energy. It helps avoid mixing up power, energy transfer and units.

transformer

transformer is a curriculum-aligned term linked to the learning objective: Recognise that detailed transformer construction and operation is covered separately in Transformers (HT only)..

detailed transformer construction

In The National Grid, detailed transformer construction means the precise GCSE Physics idea needed to recognise that detailed transformer construction and operation is covered separately in Transformers (HT only). It helps avoid mixing up power, energy transfer and units.

efficiency

efficiency is a curriculum-aligned term linked to the learning objective: Apply WS 1.4 when explaining the efficiency of power transmission..

explaining efficiency power

In The National Grid, explaining efficiency power means the precise GCSE Physics idea needed to apply WS 1.4 when explaining the efficiency of power transmission. It helps avoid mixing up power, energy transfer and units.
