6.17 Transformer

Recall the structure of a transformer, and understand that a transformer changes the size of an alternating voltage by having different numbers of turns on the input and output sides

A transformer consists of a circular iron core with input and output coils wrapped around opposite sides. In order for it to work there needs to be a changing magnetic field; this is why DC power cannot be transformed

The Java applet at this URL shows a simple transformer
