Most of us have heard of transformers. More than likely the device you are reading this on is plugged into either a 240 V or 120 V power supply, but only requires a much lower voltage. Do you have a transformer that transforms the higher voltage into the lower voltage. But how does it work? In essence it's a simple application of conservation of energy and Faraday's law. This video not only discusses the key principles but also the mathematical models associated with transformers.
Check out the sample solution, and try some problems yourself. Also watch the video on the induction coil, which is used in many classrooms and is simply a transformer. |
Check your understanding.
Another application of induction, a type of step up transformer
