Period 2 - Self-study this topic and go back to General Form of Faraday's Law topic from last cycle for today's class.

Today, we'll do some transformer problems from the textbook Chapter 31 (These should be review from last year really.)  

    Required:  62, 63, 64, 65  

With any time remaining, watch below.  This next topic is very important to understand!

Homework:  Upload all solutions to second problems above transformer problems to ✏️ Google Classroom by Sunday, March 17 at 10pm.  Quiz Friday, March 15th on all of Faraday's Law!   For the quiz, you should know Lenz's Law and Faraday's Law (including motional emf and the general form).  Make sure you're caught up with all of your work.  Watch the following videos on inductors in circuits:

Optionally, check out some practical stuff about inductors including what inductors do in series and in parallel.

Quiz Today on all of Faraday's Law!     

❤️ 2: M 3/18, 💛 4: T 3/19a, 💙7: F 3/15b - LR Circuits (1)

Daily check-in: LR Circuits

Today, after a check-in, we'll try some AP problems involving LR circuits.  We'll remember what happens to inductors at t=0 and t=∞.  We'll also calculate the energy stored in an inductor.  We'll talk about HOW energy is stored in the inductor.

    Required:  1998E2, 2008E2
    Optional Enrichment:  1988E3a, 2019aE2, 2019aE3

The optional enrichment problems are not all about induction, but they show how induction can be just part of a problem.  With any time remaining, find other AP problems to practice for your induction exam.

Homework:  Upload solutions to the two required AP problems to ✏️ Google Classroom by Tuesday, March 19th at 10pm.  Induction Exam on Thursday, March 21st.  NOTE:  If you are going away early, I'd like for you to take the test before you leave.  If you are absent on Thursday, March 21st, please plan to take the assessment during class on Friday, March 22nd (pds 2 & 7) or Friday during study hall (pd 4).

The optional enrichment problems are not all about induction, but they show how induction can be just part of a problem.  With any time remaining, find other AP problems to practice for your induction exam Tuesday.  

Homework:  Upload solutions to the two required AP problems to ✏️ Google Classroom by Tuesday, March 19th at 10pm.  Make sure you've completed all required problems up to this point.   Induction Exam on Thursday, March 21st.  NOTE:  If you are going away early, I'd like for you to take the test before you leave.  If you are absent on Thursday, March 21st, please plan to take the assessment during class on Friday, March 22nd (pds 2 & 7) or Friday during study hall (pd 4).
