"Electric potential V is the electric potential energy per unit charge: V = PE/q. The unit for electric potential, or voltage, is the volt: 1 V = 1 J/C."
"The relationship between electric potential difference and work done: ΔPE = qΔV. This is the energy that would be needed to move a charge q through a potential difference ΔV."

- Describe equipotential surfaces and explain their relationship to electric field lines
- Relate the concepts of electric potential and potential energy to the conservation of energy framework from mechanics
