electric potential
Let an agent explain electric potential, relay definitions, units, relation to fields and related electrochemical quantities from physics and electrochemistry sources, describe the named quantities and flag the misfiled alias, relay electrical safety, and distinguish electric potential from electric potential energy, electric field, electromotive force and current.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain electric potential, relay definitions, units, relation to fields and related electrochemical quantities from physics and electrochemistry sources, describe the named quantities and flag the misfiled alias, relay electrical safety, and distinguish electric potential from electric potential energy, electric field, electromotive force and current.
The electric potential energy per unit charge at a point in an electric field, a scalar quantity measured in volts, with the potential difference between two points being the voltage that drives current, related to the electric field as its negative gradient in electrostatics; related quantities the registry aliases name include electrochemical potential, combining chemical and electric terms for charged species, the Galvani potential difference between phases, and zeta potential at the slipping plane of particles in colloids, while the Mie potential names an interatomic potential energy function in molecular modelling and appears misfiled. High voltages are dangerous, and electrical work should follow safety rules.
What it is for: Describing electric energy per charge.
It can be explain definition and units; relay relation to fields; describe named quantities; relay electrical safety.
Distinguishing features
Scalar quantity

What it looks like
Not a physical object; measured with voltmeters and shown as equipotential maps.
Physical character
SI unit: volt unit - joule per coulomb
relation: E = -grad V formula - electrostatics
zeta potential stability guide: magnitude above about 30 mV often stable note - rule of thumb
How it is recognised
Electric potential energy per unit charge
Mie potential, zeta potential, electrochemical potential, Galvani potential, voltage
Potential energy depends on charge; the field is a vector; EMF is source-driven; current is charge flow; the Mie potential is interatomic
