Compound Circuits Practice

Today on bellwork we learned a trick to solve a compound circuit when there is a junction where the current does NOT split evenly. This is kind of hard to explain in a picture, so I have a video from last year that uses the same trick to solve problem #2 on your homework, which is Electricity VI.

Here's the finished bellwork too:

Solving Compound Circuits

Today we finished or notes about solving compound circuits. I go through all of the procedure in a video from last year. Your homework tonight is Concept - Development 35-2.

Overload, Circuit Breakers, and Compound Circuits

Today we first talked about the purpose of a circuit breaker or fuse and how overload happens. Then we worked on Electricity IV (below) for a bit. If you didn't finish in class, that's homework.

Later we started talking about compound circuits and how to find their total resistance, but we are going to add to and finish those notes on Thursday so I'll post them then.

Review

Welcome back from Spring Break! Today we are reviewing series and parallel circuits. Your homework is Electricity V.

AC/DC

Today we talked briefly about alternating current and direct current, as well as the war between Thomas Edison and Nikola Tesla. We also watched the Epic Rap Battle of History between those two - one of the only ERBs that is school appropriate :)



Another related video is Drunk History: Nicola Tesla. This has some bad language!

Series and Parallel Circuits

Today we named the two types of circuits you made yesterday in your lab: series and parallel. We went over the characteristics of each and did some math. Homework is Concept-Development 35-1.

Circuit Lab II

Today you are lighting two bulbs at once in a qualitative lab. First we practiced drawing circuit diagrams on bellwork, then we started Circuit Lab II. You can continue working on that tomorrow too.
