Today, recalling the outcome of the lab, we'll review the proportionality relationship between voltage, current, and resistance, which we call Ohm's Law. To confirm your results, watch the following three short videos:
Then complete the "Electric Current, Ohm's Law, & Power WSs". There is information in this packet about what you should have gained from the lab in addition to information about how to calculate the power output of a circuit element, as a review of the videos above.
Presentation: Ohm's Law, Light Bulbs, and Power
Handout: Electric Current, Ohm's Law, & Power WSs
Homework: Electric Current, Ohm's Law, & Power WSs due next class.
🟩❗5: W 4/2 - series & parallel circuits
🟩❗5: W 4/2 - series & parallel circuits
Today, we will start to look at more complex circuits - where circuit elements such as light bulbs are connected in series and parallel. We will learn to qualitatively analyze the effects on the brightness of the bulbs. We will try to determine what is happening in the circuit using our knowledge of voltage, current, and resistance. We'll practice schematic diagramming of circuits.
First, watch the video "Series and Parallel Circuits."
Then, complete "Series and Parallel (PH)" and "Simple Circuits CompuSheets".
Presentation: Series & Parallel Circuits (slides 9-24)
Printable: "Series and Parallel (PH)" and "Simple Circuits CompuSheets"
Homework: "Series and Parallel (PH)" and "Simple Circuits CompuSheets" due next class. Circuits Quiz Momentum Unit Assessment on Tuesday, April 8th.

💚 5: Th 4/3 - series and parallel circuits problems
Today, we'll work to show evidence that we understand series and parallel circuits by completing Series & Parallel Circuits Activity. In this lab, we'll explore connecting holiday lights to batteries or you can run a PhET simulation if you prefer. Create your evidence of learning, and submit to ✏️ Google Classroom by Sunday, April 6th at 10pm.
Make sure you hand in "Series and Parallel (PH)" and "Simple Circuits CompuSheets" due today in class.
Homework: Momentum Unit Assessment on Tuesday, April 8th. Series & Parallel Circuits Lab due to ✏️ Google Classroom by Sunday, April 6th at 10pm.
Optional Extra Practice: 📖Mastering Physics "Ch 23 - series & parallel circuits" problems: #5, 10, 11, 12, 15, (17), 18, 23, 56, 58.
Optional Extension Activity: First watch "Circuit Analysis: Crash Course Physics #30." The key to solving combination circuits is to *REDRAW THE CIRCUIT EVERY TIME YOU COMBINE RESISTORS* that are simply in series or simply in parallel. See my solution to the "Crash Course Circuit Analysis SOLUTION" where I re-draw every step combining resistors in series or parallel, and then I work my way backwards to find currents, voltage drops, and power. For another detailed example, look in your textbook at Example 23.9 on pages 813-814.
Then, complete the 📖 Mastering Physics "Ch 23 - combo circuits" problems: #19, 20, 25, 27, 28, 29, 31, 63, 64, 72. This is completely optional, but recommended if you are taking AT Physics next year.
