Electrical Potential

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 St. Mary’s Physics

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)

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?

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?   Practice Problems p571 do any 3 #16-20, and p572 do #21, 22 & 25
