Practice Time

The rest of the week is work time for you to finish all of your homework and to study for the test. You have one last homework, Electricity TIPERs #4, which is due tomorrow. The practice test was also available.

Electricity Test Practice
Key:


Here are some old solutions videos:

#15 (the reading HW I mention in the video wasn't done this year)


Your test is either Monday or Tuesday. You will have a little time to study before it starts.

Compound Circuits

How do you solve a circuit that has both series and parallel components? That was the topic today. We took notes by solving a problem on the board. Here is the result:


Here is a video that I made a couple of years ago solving this problem.

Whatever time we didn't spend on this problem (which is a lot of time) you were working on two worksheets: Concept-Development 35-2 and Compound Circuits Practice. Whatever you didn't finish in class is homework.

Circuit Breakers

Today we briefly talked about circuit breakers (and fuses) - how they work, why we have them, etc. Most of the day was work time, though. I need you all to get your labs done and checked.

Homework is p.644 #37, 38, 40

Electrical Power

Today we talked about electrical power.

Notes: Electrical Power

Here is the setup for the practice problem:



Homework: Concept-Development 34-2

Solving Series and Parallel Circuits

Today we solved one series and one parallel circuit together on the board:


Then you practiced on your own with the worksheet Series and Parallel Circuits Practice, which is homework if you didn't finish in class.

Circuit Lab #3 + Series and Parallel Circuits

Today you completed another conceptual lab, then we had some notes about the two arrangements of light bulbs you created.

Circuit Lab #3 + Series and Parallel Circuits

Homework is Concept-Development 35-1

Circuit Lab #2 + Ohm's Law

Today and tomorrow are modular! We are completing a quantitative lab, Circuit lab #2, then using it to derive Ohm's Law.

Lab Instructions + Ohm's Law notes

Diagrams for setting up the multimeter:


If you were gone. you may be able to complete Circuit Lab #2 with the online simulator PhET: Ohm's Law. This is pretty easy and fast to do in person, though, so you should complete it in person if at all possible.

Homework is p. 611 #10, 11, 13, 15, 20, 51

Circuit Lab #1

Today you completed a conceptual lab. The instructions and also a little bit of notes about circuit diagrams are here: Circuit Lab 1. You may also be able to complete Circuit Lab #1 with the online simulator PhET Circuit Construction Kit .

Homework is Concept-Development 34-1.

ACT

Today you all took the ACT, so I only saw 5th and 6th periods. Those were simply work time.

Monday, April 1, 2019

Electrical Resistance

Today we are talking about the last of the three fundamental quantities we need to talk about circuits.

Notes: Electric Resistance

Homework: p. 609 MC #3, 4, 14 + Problem #14

This is due on WEDNESDAY - please do not spend time on this tonight. Tonight you should be resting for the ACT, which is tomorrow.
