GCSE Physics - National Grid #20

The video explains the National Grid, a network of transformers and wires distributing electricity across the UK. Electricity is mainly generated in power stations using fossil fuels or nuclear energy. Power stations adjust output based on demand, which peaks in the evening. To minimize energy loss during transmission, high voltage is used, requiring step-up transformers. Before reaching homes, voltage is reduced by step-down transformers to ensure safety and prevent appliance damage. The process involves balancing voltage and current to efficiently transmit electricity across the country.
