A voltage is a scalar potential on the vertices of an electrical network. Away from prescribed boundary vertices it is harmonic, and its difference across an edge drives current through that edge.

Voltage, also known as electrical potential difference, is a measure of the electric potential energy per unit charge between two points in an electrical circuit. It represents the work done to move a charge from one point to another against an electric field. The unit of voltage is the volt (V), which is defined as one joule per coulomb (1 V = 1 J/C).
