Elements of passive electronic components (2):
The Iron-cored transformer
The iron-cored powertransfonner is usually looked on as simply a device for raising or lowering the voltage of an alternating supply, with a corresponding decrease or increase in the current, but there is more to its functions in life than this simplistic view suggests. The transformer is an electromagnetic energy converter, whose operation is explainable in terms of the behaviourof a magnetic circuit excited by an alternating or chan ging current. As such, a brief review of its operational behaviour as a passive electronic component, is justified.This article is one from our 90s collection, the articles are downloadable as a PDF for all our members. Although the information we have on the website is a little less rich than you have become used to since 2000, the articles themselves are still a good read. Please enjoy the professionally designed, easy to build circuits that were considered the latest developments in electronics and information technology at the time they were written. In most cases they have stood the test of time pretty well.
