🔴 2: M 1/29a, 🟡 4: F 1/26, 🔵7: F 1/26 - RC circuits problems (3)

Today, continue working on the following problems.  These are learning problems, so we will be learning and deepening our understanding of capacitors while we do problems.

    Required 2:  Ch 27 #61, 63, 65, 67, 79, 80, 2006E2, 1996E2, 2010E2
    Enrichment: Ch 27 #66, 69

Also, after learning a little more, I would like for you to revisit the "Tricky Challenge" from the ✅ GoFormative "Capacitor Pre-Lab".  There's a new assignment in ✅ GoFormative called "Capacitor Pre-Lab Revisited".

HomeworkQUIZ Monday, January 29rd on derivation of charging and discharging equations.  Upload pictures of your solutions the problems above (required 2) in ✏️ Google Classroom by Monday, January 29th at 10pm.  ✅ GoFormative "Capacitor Pre-Lab Revisited" also due on Monday, January 29th at 10pm.

🟥❗ 2: M 1/29b, 🟨❗ 4: M 1/29, 🟦❗ 7: M 1/29a - ✏️dielectrics

QUIZ on derivation of charging and discharging equations TODAY.  

Today, we'll talk about how dielectrics can increase capacitance.  We'll look at the work to insert or remove a dielectric with a problem.  Watch the following video for details on dielectrics.  Then do problems from the Giancoli textbook Chapter 24:

   Required 3: Giancoli Ch 24 Example 24-8 and Problems #56, 57, 85, 87

Here's a list of the things you should be able to do by now:

Short QUIZ on RC Circuits TODAY  (marking period 3).

Today, after the quiz, we'll continue to do the lab where we explore the terms: emf, internal resistance, and terminal voltage. 

Safety Precautions:

After finishing the lab, do textbook problems Chapter 27 #10, 14 and Giancoli Chapter 26 #1, 2, 4.  Then do 2015E2 to check for your understanding.  Watch the homework videos first if you prefer.
