Electrostatics Assessment TODAY!

### π 1: W 1/19b, π 3: Th 1/20 - time-dependent RC circuits

Today, we'll learn what a capacitor does when it's in a circuit. This PhET simulation will assist with our investigation. We will compare and contrast a capacitor with a battery. Then, we'll use Kirchhoff's Laws to determine an expression for the charge of a capacitor as time changes.

Then, we will collaborate to understand Jon Ting's video by forming heterogeneous groups/pairs to ensure everyone understood the derivation. After you understand the video, do the derivations yourself on a separate sheet of paper to be turned in in class on Monday, January 24th.

Homework: Read sections 27-3 & 27-4 in your textbook. Rewatch Jon Ting's video.

### π΄ 1: F 1/21, π‘π¨ 3: F 1/21 - capacitor pre-lab

Today, we'll practice the derivation of the charge on a capacitor over time (charging and discharging) as well as the currents over time. Submit a picture of your work to βοΈ Google Classroom.

Then, we'll complete Capacitor Pre-Lab in β GoFormative.com utilizing what you learned from South alumnus Jon Ting's video on how to use Kirchhoff's Laws to determine an expression for the charge of a capacitor as time changes.

Homework: Quiz on equivalent resistance (combo circuits) and Kirchhoff's Laws next class - Monday, January 24th. Submit a your derivation of charging and discharging equations in class next time Monday, January 24th. If you did not finish the pre-lab in β GoFormative.com above, do so by Sunday at 10pm.
