More on Electric Potential
This lecture is based on Serway, Sections 25.1-25.8.
- One can use the electric potential/altitude analogy to solve
some difficult problems qualitatively
- Electric potential between two points is independent of the
path taken between them (because electric force is
conservative)
- Electric potential is constant along equipotential surfaces
- If you know the electric field and want to find the electric
potential between points A and B, integrate
the electric field strength
along a line -- any line -- between A and B
- If you know the electric potential and want to find the
electric field at some point, take the gradient
of the potential, evaluated at that point
