Electromagnetics & Signals Course ⚡ Electrostatics I: Coulomb's Law, Gauss's Law & Potential
🔒

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
