Exploring the Relationship Between Voltage and Electric Fields

In summary, voltage is a measure of electrical potential and does not require the flow of electrons to exist. However, an energized capacitor can have a potential difference, or voltage, between its plates, which also creates an electric field between the plates. This is similar to how current creates a magnetic field. Therefore, voltage is a result of an electric field, rather than creating one itself.

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.)

Related to Exploring the Relationship Between Voltage and Electric Fields

1. What is voltage?

Voltage is a measure of the electric potential difference between two points in an electrical circuit. It is often described as the "pressure" or "force" that drives electrical current.

2. How is voltage produced?

Voltage is produced by the separation of positive and negative charges. This can occur naturally, such as in the case of lightning, or artificially, through the use of batteries or generators.

3. What is an electric field?

An electric field is a region in space where an electric charge experiences a force. It is produced by the presence of a voltage or by the movement of charged particles.

4. How does voltage produce a field?

When a voltage is applied to a conductor, it creates an electric field around the conductor. This field exerts a force on any charged particles within it, causing them to move and creating an electric current.

5. What is the relationship between voltage and electric field?

Voltage and electric field are closely related. Voltage is the cause of an electric field, and the strength of the electric field is directly proportional to the voltage. In other words, the higher the voltage, the stronger the electric field.
