GCSE Physics - How Transformers Work #82

The video explains how electricity is generated and distributed in the UK using the National Grid. It highlights the role of transformers in increasing and decreasing voltage to minimize energy loss. The video details the components of a transformer, including the iron core and coils, and describes the process of transferring electricity through induced magnetic fields. It also explains how transformers adjust voltage levels based on the number of coil turns, using examples of step-up and step-down transformers.
