The Step Down Transformer Working Model is an educational science project designed to demonstrate the working principle of a transformer and the conversion of high AC voltage into low AC voltage. This model clearly explains how electrical energy is transferred between primary and secondary coils through electromagnetic induction. The model converts 220V AC input into 6V AC output, making it an excellent learning tool for understanding transformer operation, electromagnetic induction, voltage transformation, and power transmission concepts. It is ideal for school science exhibitions, physics practicals, STEM learning, and engineering demonstrations.
