A fully resourced GCSE Physics lesson covering transformers, electromagnetic induction and the National Grid. This lesson teaches pupils how electricity is transmitted efficiently across the UK and why step-up and step-down transformers are essential for reducing energy loss and making electricity safe for domestic use.

The PowerPoint introduces key concepts including voltage, current, resistance, power, transformer structure, alternating current, induction, transmission cables and National Grid efficiency. The matching workbook develops this knowledge through calculation practice, terminology tasks, diagram labelling, multiple-choice checks and extended evaluation questions.

Designed for mixed-ability GCSE learners, this resource combines clear scientific explanations, accurate formulas and GCSE-style application tasks.
