Transformer construction

A transformer uses electromagnetic induction to change an alternating potential difference. The primary coil is connected to the input supply, and the separate secondary coil is connected to the output circuit.
Step-by-step lessons covering AQA GCSE Physics 7.3.4 Transformers (HT only) for Foundation and Higher tier. Each lesson works through exam-style questions in Paper 1 and Paper 2 format. Build a strong grip on equations, units and Key Stage 3 fundamentals before tackling the more demanding topics like electromagnetism, the particle model of matter and space physics.
