How does a transformer change voltage?: 　　The transformer is made based on electromagnetic induction. It consists of an iron core made of silicon steel sheets (or silicon steel sheets) and two sets of coils wound on the iron core. The iron core and the coils are insulated from each other and have no electrical connection. We call the coil connected to the transformer and the power supply side the primary coil (or the original side), and the transformer and the power supply side the primary coil (or the original side)....; Keywords： transformer
