e-Learning for 4 ChPh: Last Topic!!

Happy Tuesday, one and all!! I hope you are well, and good health for you and your families! A good way to start each day is to think of something you appreciate; or think of something nice you have done for someone else the past day or two; or think about something nice someone did for you! Remember counselors, social workers and school psychologists and nurses remain available for anyone.

Some housekeeping items:

• be sure to vote for senior awards
• please keep checking in daily with the school on the Google Form
• the school is supposed to get more logistics answers for AP Exams by April 3, but for us plan on material covered being through electricity: electrostatics with point charges, equipotentials, Gauss, non-Gauss, resistor circuits, capacitors (w/ dielectrics), RC circuits; sounds like all free response so you have to show work, password protected files for the exam, 45 minutes long, I suspect a lot of Honor System built in to this. You can start review any time, and a good initial guide is our EM Objectives. There are all sorts of review sets in the 4 Chem/Phys folder. You can start looking over old material in any of your AP classes any time. Colleges should still be sticking to their policies about giving credit, placement, etc., according to the College Board. 
• please email me with updates on any practice problems you have been trying. Because almost all of them are old AP problems, you can be self-checking/grading to see how you are doing, but please let me know and any questions you may have. You can also pose questions to the learning team, as well as share fun things to try while quarantined. 

EM Induction is your last physics topic! We have one last item within induction, and that is an application in circuits: what happens when we put inductors, which are essentially little solenoids, into circuits with resistors, and finally when we combine inductors with capacitors? We will even throw in a blurb about transformers, and end with Maxwell's equations - and how did Maxwell predict light is an EM wave, and he even predicted the speed of light, decades before this was proven experimentally, just from math?!?!

Your last bit of physics is in Packet #4. The relevant videos for all this are: 

- Maxwell's displacement current: how capacitors really work, and how a changing E-field behaves just like a current

- Inductors in series with resistors (RL circuit)

- Inductors in parallel with resistors

- Last circuit: LC Circuits, the heart and soul of wireless technology!

- Supplemental: The basics of inductors from an engineer's point of view

- Supplemental: How does a transformer work

- Maxwell's equations and EM waves: everything in E&M comes together!

Practice problems are in Packet #4. This includes a lab using a PhET simulation - I hope it works on your ChromeBook! There are some good explanations, examples, diagrams in your textbook for all the induction topics.
