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" in β GoFormative.
Printable: "Series and Parallel (PH)" and "Simple Circuits CompuSheets" (but complete both for credit in β GoFormative)
Homework: If you have not watched the video "Series and Parallel Circuits," please make sure to complete that before next class. "Series and Parallel (PH)" and "Simple Circuits CompuSheets" in β GoFormative are due Tuesday by 10pm. No late work accepted in β GoFormative.
Today, we'll use Ohm's Law and equations for equivalent resistance in series and parallel circuits to solve combination circuits.
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.
Then, complete the worksheet "Combo Circuits (PH)" in β GoFormative. Finally, we'll practice combo circuit problems by doing β Positive Physics unit 20: circuit analysis "work" problems from the section:
challenge 2 (4 problems)
Homework: "Combo Circuits (PH)" in β GoFormative is due on Wednesday at 10pm. Finish these β Positive Physics problems by Friday at 10pm. Only completion score counts. No late work will be accepted.
Optional Extra Practice: Combo Circuits CompuSheet (SOLUTIONS)
Today, we'll introduce the concept of magnetism. Watch the three videos below:
Then complete two β GoFormative assignments:
"Intro to Magnetism (PH)"
"Questions on Magnetic Field Lines"
Homework: Finish both β GoFormatives by Sunday at 10pm. No late work accepted on GoFormatives. β Positive Physics QUIZ on Circuits unit 20 challenge 2 on Tuesday, June 2nd!
