1. Electrical Potential

2. The Electric Potential Difference
between two points in an electric field is
- the work required to move a unit charge as a charged particle is moved between the points
the change in potential energy per unit charge
as a charged particle is moved between the points

4. Potential difference (potential drop) in an electric field is the change in energy per unit charge.  
V = W q
V = potential difference (volts)
W = work (joules)
q = charge (coulombs)

5. Two large charged parallel plates are 4. 0 cm apart
Two large charged parallel plates are 4.0 cm apart. The magnitude of the electric field between them is 625 N/C.
What is the potential difference between the plates?
b) What work is done moving a charge equal to that of one electron from one plate to another?

6. Practice Problems p571 do any 3 #16-20, and p572 do #21, 22 & 25
A voltmeter measures the potential difference between two large parallel plates to be 60.0 V. The plates are 3.0 cm apart.
What is the magnitude of the electric field between them?
