๐ข 5: T 6/6, ๐ต 7: W 6/7 - ๐๐ย 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
๐ฉ 5: W 6/7, ๐ฆ 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:
Check out this homemade generator:
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
