Electric Potential & Potential Energy
Inside this lesson
- Define electric potential V as potential energy per unit charge, V = U/q
- Compute the potential of a point charge using V = kQ/r with V = 0 at infinity
- Relate the electric field to the potential through E = −∇V
- Calculate the potential energy of a pair of point charges using U = kQ1Q2/r
