📄 generators

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

Here's how generators work:

📄 power lost in transport

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

Resistor 1 is the power line.
Resistor 2 is the appliance that you plug in.

motors

Today, we'll try to use what we know about generators to try to understand motors. How are motors and generators the same? How are they different? After walking through how motors work as a class, you'll take some time to write a paragraph about how a motor works. Use your guided explanation of generators as guide to explaining how motors work. If you need help, watch the following video:

Then, we'll use some simple tools to create your own motor. We'll think about what we've learned so far in this unit in order to design an optimal motor given the materials.

Homework: Submit your paragraph on how a motor works to ✏️ Google Classroom by Friday at 10pm. Be sure not to plagiarize! Put it in your own words (not the words of your textbook, the internet, ChatGPT, a friend, etc.). Students who get a physical motor working during class are exempt from this assignment!
