Quiz Today on all of Faraday's Law!
Today, after the quiz, we'll do some transformer problems from the textbook Chapter 31 (These should be review from last year really. If you're totally bored by these, find other problems on previous topics.)
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 3 AP problems to βοΈ Google Classroom by Tuesday, March 23rd at 10pm. 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.
π₯ 1: F 3/25 lab, π¨ 3: Th 3/24 lab - LR Circuits (1)
π₯ 1: F 3/25 lab, π¨ 3: Th 3/24 lab - 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=β. 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 Tuesday.
Homework: Upload solutions to the two required AP problems to βοΈ Google Classroom by Sunday at 10pm. Make sure you've completed all required problems up to this point. Induction Exam on Tuesday, March 29th.
If you need any help with inductor problems, check out this basic problem:
For a more complex example problem, watch the following (inductor starts around 3:38):
β€οΈ 1: M 3/28, π 3: F 3/25 - Maxwell's equations
β€οΈ 1: M 3/28, π 3: F 3/25 - Maxwell's equations
Today, 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
These 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 next class.
Homework: Induction Exam next class - Tuesday, March 29th.
