Chapter 20 Electric Potential and Electric Potential Energy Flashcards
1
Q
Electric Potential Energy
and the Electric Potential
A
o There is a uniform field
between the two plates
o As the charge moves
from A to B, work is
done on it
o W = Fd= q Ex (xf – xi) = ΔKE
o ΔPE = - W
o = - q Ex (xf – xi)
o only for a uniform field
2
Q
The potential difference between points A and B is defined as
A
the change in the potential energy of a charge q moved from
A to B divided by the size of the charge
3
Q
Potential Difference Equation
A
ΔV = VB – VA = ΔPE / q
