AT Cycle 30

🔴❗ 2: T 3/18, 🟡❗ 4: T 3/18, 🔵❗ 8: T 3/18 - transformer problems

Quiz Today on all of Faraday's Law! 

Today, we'll do some transformer problems from the textbook Chapter 31 (These should be review from last year really.  Mostly, know how to use the ideal transformer equations.)  

    Required:  62, 63, 64, 65  

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

Homework:  Finish transformer problems.  Watch the very important inductor videos below.

🟥 2: Th 3/20 lab, 🟨 4: W 3/19 lab, 🟦 8: W 3/19 lab - LR Circuits

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:  Finish AP problems above.  Induction Exam on Monday, March 24th.  

❤️ 2: F 3/21, 💛 4: Th 3/20, 💙 8: Th 3/20 - Maxwell's equations

Today, we'll finish out E&M with one final lesson.  We'll look at how Maxwell brought everything about electric and magnetic fields together in what we now call "Maxwell's Equations."

• We'll learn about displacement current to complete Ampere's Law.

• We'll learn about how energy is stored in electric and magnetic fields.

• We'll learn about the symmetry in the mutual creation of electric and magnetic fields.

• And we'll learn the coolest thing about electric and magnetic fields IMO.

Then, if there's time, we'll do some practice problems collaboratively during class:

    Optional Enrichment:  1988E3a, 2019aE2, 2019aE3

Homework:  Study for Induction Exam next class - Monday, March 24th.
