GCSE Physics · key term
A network of cables and transformers that transfers electrical power from power stations to consumers.
Used by AQA, Edexcel and OCR
Specification 4.2.4.3 · Paper 1
Revise: The National GridThe National Grid links these power stations to consumers through a network of cables and transformers. Electrical power is transferred through this network rather than being produced separately beside every consumer.
Specification 10.25, 13.8, 13.9 · Paper 2
The network of cables and transformers that transfers electricity from power stations to consumers across the country.
Revise: Reducing Unwanted Energy TransferA second way to reduce heating losses is to reduce the current. This is especially important in the long transmission lines of the National Grid, where even a small resistance can lead to a significant total energy transfer.
The network of cables and other equipment that transfers electrical energy from power stations to consumers across the country.
A system of high-voltage cables and transformers that transfers electrical power from power stations to consumers.
Specification P8.2c, P8.2e · Paper 2 (Foundation), Paper 4 (Higher)
A network of cables that transfers electrical power from power stations to places where it is used.
Revise: National GridThe National Grid is the network that transfers electrical power around the country. Electrical power tells us how quickly energy is transferred.
The network of cables and transformers that transfers electrical power from power stations to places where it is used.
Paper 1, Paper 2
The network of cables and transformers that transfers electrical power from power stations to consumers across the country.
Revise: Methods of Generation and the National GridPower stations may be far from the homes and workplaces using their output, so the National Grid transfers electrical power across the country using cables and transformers.
The network that transfers electrical energy from power stations to consumers using transformers and transmission cables.
For National Grid questions, link high voltage to lower current and then to less heating in the transmission lines.
For National Grid explanations, link every step: higher potential difference → lower current for the same power → less heating of cables because .
