The transformer is a ____ electrical device that transfers power from one circuit to another from which it is electrically isolated, but magnetically attached by a laminated steel core. This transfer is done without a change in frequency and most of the time with a change in voltage and current. The transformer is a static electrical device that transfers ____ from one circuit to another from which it is electrically isolated, but magnetically attached by a laminated steel core. This transfer is done without a change in frequency and most of the time with a change in voltage and current.
