Practice QUIZ on Lenz's Law TODAY!   This will not count for a grade.  You don't need to make this one up if you miss it, but you can if you want.  

Today, we'll see how transformers work and how they can be useful.   We'll use Faraday's Law of Induction to derive the relationships between primary/secondary numbers of coils, voltage, and current in ideal transformers.  

This video helps to explain how a transformer works (in case you miss class)
