DC Voltage Source

This type of source specifies the total DC voltage (electric potential) on a conductor. Voltages can be defined as constants or as math functions; however, the potential on a conductor is constant over the entire conductor. Note that conductors that touch should be set to the same voltage or defined as a single voltage source, since their potentials are identical.

DC voltage may also be specified on an edge or edges. Voltages can be defined as constant or as functions of position (for instance, to model a specific distribution of potential on the surface of a dielectric).
