2: Th 1/25 lab, 4: F 1/26 lab

Today, we'll do a lab where we explore the terms: emf, internal resistance, and terminal voltage

After finishing the lab, do textbook problems Chapter 26 #1, 2, 4.  Then do 2015E2 to check for your understanding.  Watch the homework videos first if you prefer.  

Homework:  Finish the lab.  If you have any trouble understanding the analysis, watch the following video:

Finding Internal Resistance and EMF of a Battery (JCS)

Then watch this video on maximizing the power for an external resistor:
