Quiz Today on Gauss's Law.

Daily Check-In: Electric Potential due to continuous distribution of charge

Today, we'll do the following problems from Chapter 24 on calculating potential due to a continuous distribution of charge:

Required: 23, 24, 30, 32, 33

With time remaining, you may watch the video below or find more problems to do.

Homework: QUIZ on Electric Potential with both integral and path integral (no equipotential lines) Wednesday, January 5th! Upload your solutions to the above problems to Google Classroom by Monday, January 3rd at 10pm. Catch up on anything you have not completed yet including watching videos and doing required problems. Write down any questions you have. Check out the Circuits Review Videos in preparation for the next unit which we will start the second week of January.

Period 3 only Homework: Watch the following video on electric potential with the path integral. We use this method when we know that function for electric field for all points in space, which is usually in those symmetric situations when we used Gauss's Law.

### π₯ 1: M 1/3 lab, π¨ 3: Th 12/23 lab - electric potential path integral

Period 1 only - We'll spend the first 20 minutes of class watching the following video on electric potential with the path integral. We use this method when we know that function for electric field for all points in space, which is usually in those symmetric situations when we used Gauss's Law.

Daily Check-in: Finding potential with path integral

After the daily check-in, we'll continue working on electrostatics problems to review finding both electric field and potential.

Required: 1979E1, 2000E2, 1994E1, 1993E1, 1989E1, 1980E2
Enrichment: Find old AP problems in the resources I provided in Google Classroom. There is at least one electrostatics problem from every year of past AP problems.

Homework: QUIZ on Electric Potential with both integral and path integral (no equipotential lines) next class - Wednesday, January 5th! Check out the Circuits Review Videos in preparation for the next unit which we will start the second week of January.

### β€οΈ 1: T 1/4, π 3: M 1/3 - equipotential lines lab (1)

Today, we'll learn how to draw equipotential lines with a lab. We'll continue with the lab next hour.

Virtual Lab Option: If you are absent or miss the lab for some reason, do the following alternative lab. Read the instructions for the equipotential lines lab, and complete the questions in the βοΈ Google Classroom assignment, which will require you to screenshot your work, posting it on a Jamboard, and then drawing electric field lines overtop.

Homework: Study for QUIZ on Electric Potential with both integral and path integral (no equipotential lines) next class - Wednesday, January 5th! The equipotential lab is due Wednesday at 10pm.
