2. What’s up? This week we cover the topic of potential Quiz on Friday
Potential Energy, Potential
Capacitance (Finally, an experiment!)
Quiz on Friday
Potential
EXAMINATION #1
Next Wednesday
Chapters 18 & 19 (as far as we get)
Start reading Chapter 19 and watch for a WebAssign.

3. Let’s do a WA problem …..
The drawings show three charges that have the same magnitude but different signs. In all cases the distance d between the charges is the same. The magnitude of the charges is |q|= 4.2 µC, and the distance between them is d = 1 mm. Determine the magnitude of the net force on charge 2 for drawing #c. NOTE: ONLY MAGNITUDE IS REQUESTED,
2.24e+05

6. Today We begin Chapter 19 – Electric Potential
We will apply energy concepts to charges and collections of charges.
We will discuss the potential energy of a charge at a point.
We will DEFINE the PE of a charge at a point PER UNIT CHARGE (Like E) and call that POTENTIAL
The Units of potential will be called VOLTS
We will then do EXPERIMENTS with capacitors
Next Wednesday will be the first examination.
It will cover everything we do through Next Monday.
Begin reading chapter 19 and it would help to begin a review chapter 18 as well.
