Potentials of zero charge
Web12 Jan 2024 · The surface tension γ reaches its maximum at the potential of zero charge, φpzc. The change with the electrode potential φ is given by Equation 1, where σ is the surface charge density, and C the interfacial … Web17 Jul 2024 · You could place a positive charge at the shown equipotential line and say that zero (electrical) potential energy is stored. Then surely, the charge will want to move towards the neighbour locations where the potential energy stored is less than zero.
