Summary
Definition of voltage in a static electric field E. The work required to move the infinitesimal test charge q from point a to b, divided by the magnitude of the test charge, is the voltage between a and b. The work, and so the voltage, is independent of the path taken in a static field. In a time-varying field, the work depends on the path and voltage is then not uniquely defined.
