### ๐ข 5: T 6/6, ๐ต 7: W 6/7 - ๐๐ย  transformers

Today, we'll see how transformers work and how they can be useful. ย  We'll use Faraday's Law of Induction to derive the relationships between primary/secondary numbers of coils, voltage, and current in ideal transformers.ย  (Know the ideal transformer equation.)

Watch this video on how transformers work:

You can check out this demo to see a transformer in action:

Then, we'll practice ideal transformer problems by doing page 1 only of ๐ Transformers WS (PH). Finally, we'll do just a few additional transformer problems from section 26.2 in your textbook with ๐ Mastering Physics "Ch26 - transformers" problems #9, 11, 12.ย ย

Presentation:ย  Electromagnetic Induction Presentation continued

Homework:ย  Complete page 1 only of ๐ Transformers WS (PH) and finish the above ๐ Mastering Physics problems by Thursday at 10pm.ย  Unit Assessment on all of Electromagnetism on Tuesday, June 13th.ย ย

Optional Extra Practice:ย  Another transformer video.ย  Do page 2 of FYP: Electromagnetism (ANSWERS).ย ย

### ๐ฉ 5: W 6/7, ๐ฆ 7: Th 6/8 - ๐ generators

Today, we'll take a look at how generators work.ย  We'll explore some real life generators and do a ๐ Thinking Lab about Generators.ย  By doing this lab, you should have a good idea about how generators work.ย

Here's how generators work:

Homework:ย  Finishย  Thinking Lab about Generators to be turned in the day of the unit assessment.ย  Unit Assessment on all of Electromagnetism on Tuesday, June 13th.ย

### ๐ 5: F 6/9, ๐ 7: F 6/9 - ๐ power lost in transport

Seniors have Senior Awards 9:30-11:30am.ย  Period 5 Sophomores have Class Elections 9:10-10:35am.ย  If you are not in class, you will need to do this on your own time.

Happy Prom! ๐

Today, we'll review concepts from last unit on circuits to answer questions about power transmission.ย  You may read page 922 in y v our textbook to start.ย  Write out your own solution to example 26.3 on that page.ย  Then do page 2 of ๐ Transformers WS (PH) which was handed out a couple classes ago.ย  Finally, complete the questions in โ Formative.com based on ย Power Lost in the Transport of Power after reading the first two pages of this packet.ย  Imagine the circuit in the questions is an AC circuit with two resistors as shown:

Homework:ย  Complete ๐ Transformers WS (PH) ย for collection on the day of the unit assessment.ย  Complete the questions in โ Formative.com based on ย Power Lost in the Transport of Power due Tuesday, June 13th at 10pm.ย  No late work accepted in Formative.ย  Unit Assessment on all of Electromagnetism on Tuesday, June 13th.ย ย
