Transformers - Edexcel Transformers use electromagnetic induction to change the voltage of alternating currents. The voltage and current changes can be calculated, as the power transfer is constant.

Electromagnetic induction can create a voltage by movement of a conductor in a magnetic field. This voltage can make current flow. Transformers use electromagnetic induction to change the voltage ...
