Electric potential and Voltage
... Voltage can only be defined for two points (nodes, terminals etc.) Voltage of a single node in the circuit does not make sense. Potential can be used to characterize a single node provided that the zero (ground) node is defined. For two points 1 and 2 with the potentials ϕ1 and ϕ2 in a circuit, t ...
