PERIOD 1: We did what everyone else did Monday. You will also have tomorrow to work on Compound Circuits Practice and Electricity TIPERs #6.
EVERYONE ELSE: We talked for 5-10 minutes about the difference between alternating current (AC) and direct current (DC). There's a great explanation on MIT's Ask and Engineer.
I also told you the story of the battle between AC and DC when this country was first building its electrical infrastructure. SciShow has a nice video about Nikola Tesla that covers some of that. There is also an Epic Rap Battles of History and a Drunk History that tell the story, although not in a way that is school appropriate so we didn't watch those.
After that you started working on your Electricity Practice Test. I have some solution videos below and the abridged solutions are here.
