Understanding Transformers: Key Concepts for Educators

Transformers are essential devices in electrical systems, operating on mutual induction to convert alternating voltage levels. They consist of a primary coil, secondary coil, and magnetic core to enhance efficiency. By maintaining the power transformation ratio, the device ensures energy conservation while minimizing losses through optimized coil arrangement, resistance reduction, and laminated cores. Step-up transformers increase voltage while lowering current, and step-down transformers do...
