### 🟢 5: M 4/1 - electric current information

Today, we’ll start Unit 9 and talk about what makes current flow. We’ll relate circuits to the concepts of electric fields and electric potential.

If you were absent or need a review, watch the first 12 minutes of the "Electric Current Introduction" video to learn how circuits relate to the concepts of electric fields and electric potential.

Then, we'll do a lab where you will construct the relationship between voltage, current, and resistance.  You will record your data and analysis in the lab in ↩️ Pivot Interactives called "Current and Voltage in Conductors (in-person)".  We'll have time next class to finish getting data or do analysis.  If you are not present for either day of the lab, you'll do the lab in ↩️ Pivot Interactives called "Current and Voltage in Conductors (virtual)".

For this lab, you will fill out a 📄 Collaborative Team Member Self-AssessmentMake sure to write your goals first.

Homework:  Either ↩️ Pivot lab due by Sunday, April 7th by 10pm.  No late work accepted in Pivot.  QUIZ on Electric Potential Energy & Potential on Thursday, April 4th!

### 🟩 5: T 4/2 - electrostatics review (sub-study)

We've seen a lot of new and difficult concepts this unit, so we'll start today by trying to figure out how all these concepts relate to each other.  We'll print and fill out this graphic organizer: "📄Electrostatic Information" which will help us to organize the way we think about each concept. You can check the answers on slide 2 of the "Electrostatics Example Problems" presentation.  You'll have the opportunity today to finish your 📖 Mastering Physics "Ch 21 - electric potential energy & potential" textbook problems #6, 7, 8, 11, 18, 19, 27, 74, 75, 80, and then ask any questions you have about these before the upcoming assessment.  Once you've completed the assignment, you may work on some of the optional work below.

HomeworkStudy for QUIZ on Electric Potential Energy & Potential next class - Thursday, April 4th!  📖 Mastering Physics "Ch 21 - electric potential energy & potential" due Tuesday, April 2nd at 10pm.  Email me with questions about any of this material.

Handout: 📄Electrostatic Information (no, you will NOT be able to use this on your test but it will help you organize the formulas in your mind, but...)

The following will be given for reference on the assessment.

Because I'm giving you these formulas, expect the questions on the assessment to be more conceptual; the questions will require deep understanding of the concepts rather than just plugging in numbers to a formula.

Optional Extra Credit:  You should probably do these if you're planning on taking AT Physics next year.  📖 Mastering Physics "Extra Credit - Ch 20-21 -  Electric Field and Potential in 2D" textbook problems Ch 20 #30, 53, plus "electric field due to multiple point charges" and Ch 21 #63, 67, 71, 72.  Remember the Principle of Superposition, and also remember that electric fields are vectors while electric potential is a scalar.  Assignment due Tuesday, April 2nd at 10pm.  Absolutely no late work will be accepted past 10:00:00pm, NO EXCEPTIONS.

Optional Extra Practice:  Try some of the other problems in "Electrostatics Example Problems"Here are my written out solutions:  Solutions to 1-4Solution to TV tube problem involving projectile motion between two parallel plates.
