Electric Potential

18.4

"We now define the **electric potential** *V*, which is the electric potential energy per unit charge." "Normally, the electric potential is simply called the *potential* or ***voltage***. The units for the potential are J/C, which are given the name *volt* (V) after the Italian physicist Alessandro Volta (1745–1827)."

What you'll learn

  1. Define electric potential energy and electric potential (voltage), distinguishing between the two
  2. Calculate the electric potential at a point due to a point charge using V = kq/r
  3. Determine the work done moving a charge between two points at different electric potentials using W = qΔV
  4. Describe equipotential surfaces and explain their relationship to electric field lines
  5. Relate the concepts of electric potential and potential energy to the conservation of energy framework from mechanics
