How Do Transformers Work?
In this video, Karen talks about how transformers work. When current passes through a wire, an electromagnetic field is formed. As that field changes, forming or collapsing, it creates electromotive force which can cause electrons in nearby conductors to move. This is how induction works. Transformers work through mutual induction, where current passes through a primary coil and INDUCES current in a secondary coil. In this way, power can be transferred and transformed without needing a physical, electrical connection. Check out the video as Karen dives deeper into the science of why and how this works as well as the uses for transformers.
