Does voltage produce a field?

    Does voltage produce a physical field, like how a current produces a magnetic field?

    Is there a field around a battery?

    Current is a measure of flow of electrons and that produces a magnetic field.
    Voltage is a measure of electrical potential, no electrons need to flow anywhere for a voltage, so no field

    Voltage is a measure of potential or potential difference in an electric field.
    If there is potential difference there is an electric field.
    But I won't say that the field is "produced" by the potential difference. Both potential and intensity of the field are just quantities used to describe the field. None of them "produce" the field.
    Same as matter is not produced by density or motion is not "produced" by speed.

    don't be so sure of that :wink:

    an energised capacitor has a potential difference between/across the plates
    it also has an electric field between the plates

    I'm under the impression that a voltage is a result of an electric or magnetic field, not that it creates a field.

    Charge produces an electric field (and the associated potential, i.e. voltage), like how a current produces a magnetic field (and the associated magnetic vector potential).

    (If you didn't intend "physical field" to mean "electric field", then you should explain what it means to you.)
