FAQ

Those who are looking for an answer to the question «Zero electric potential but non-zero electric field?» often ask the following questions:

👉 Is electric potential zero when electric field is zero?

Yes, electric potential can be zero at a point even when the electric field is not zero at that point. Considering the case of the electric dipole will help us understand this concept.

👉 Electric potential and field strength = zero ?

Youre talking about masses in the opening sentence - there wont be a point where the potential is zero. There will be a point where the field strngth is zero . Th electric field strength is related to the GRADIENT of the potential. ie whenever the potential is max or min, the field strength and hence the resultant force is zero. 0.

👉 Electric potential when electric field is zero?

Is electric potential zero when electric field is zero? If the electric field is zero, then the potential has no gradient i.e.: the potential is equal across space. But potential is always measured relative to a baseline, so it can therefore be considered as zero. Where is the electric potential zero?

Hence the physical significance of a point where the electric field is non-zero, is that the electric field is non-zero, and that the potential is zero there has no physical significance, because the point-values of the potential are not unique.

Clearly the electric field midpoint between the charges is not zero. And you are also correct that the electric potential is zero if zero potential is set at infinity, provided that the point at infinity lies in the plane into the page midpoint between the charges. That's because a plane midpoint between the equal and opposite charges ...

A) Both the electric field and the electric potential are zero. B) The electric field is zero but the electric potential is not. C) The electric potential is zero but the electric field is not. D) Both the electric field and the electric potential are non-zero. E) The net force on a negative charge is zero but on a positive charge it is non ...

The electrical potential goes as 1/r, but your reasoning is correct. You could also consider the electric potential and electric fields associated with spherical conductors: Provided the conductor is closed, the E field inside is 0 but the potential is a constant.

Yes, electric potential can be zero at a point even when the electric field is not zero at that point. Considering the case of the electric dipole will help us understand this concept. At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential is zero.

1. Inside uncharged spherical shell and charged conductor electric field is zero but electric potential cannot zero. 2. Between the line joining two similar charges of equal magnitude.

The relation between electric field and potential is given as . E = − d x d V The condition can be thought of a two identical charges separated by a certain distance. In the middle of the two point charges the electric field is zero but not the potential difference.

E=dV/dr where 'r' is the separation from the charge. When E=0, dV/dr=0 which implies that V is constant, thus it may or may not be 0. One example is the perpendicular bisector of the axis joining two similar charges (same charge); the electric field is zero on that line while potential is non-zero.

In the example given in the question, the potential is zero in the mid-point, but it changes quite rapidly when one moves towards one charge or the other. So, although the electric potential is zero, the field is nonzero. Let me try to explain by analogy. The case of a car on a road is analogous to this. The elevation of the car from sea level determines is analogous to the electric potential (it is the gravitational potential), and the force on the car is analogous to the electric field.

electric field due to the charges at that same point is non-zero. Both the electric field vectors will point in the direction of the negative charge. 3. (a) Zero. The potential at infinity is zero, and the potential at the midpoint of the dipole, due to the charges on the dipole, is also zero. The potential difference is zero, so no net work is ...

How can there be electric potential with zero electric field energy?

The same is the case for electrical potential energies. You could place a positive charge at the shown equipotential line and say that zero (electrical) potential energy is stored. Then surely, the charge will want to move towards the neighbour locations where the potential energy stored is less than zero.

How can there be electric potential with zero electric field will?

Answered 4 years ago. The electric field is vector quantity whereas the electric potential is a scalar this it's not nessecary that when electric field is zero the potential is also zero.Analogous to the example of velocity and speed. As well as we very well know that E=dV/dR where R is the distance of separation.

If the electric field is zero what is the potential?

(a) No, just because the electric field is zero at a particular point, it does not necessarily mean that the electric potential is zero at that point. At the midpoint between the charges, the electric potential due to the charges is zero, but the electric field due to the charges at that same point is non-zero.

Why is electric potential zero?

Absolute electrical potential is meaningless in electrical engineering contexts because circuits involve electrical current flowing from a high-potential point to a low-potential point and not to a no-potential point. Therefore electrical engineers talk about Voltage and not electrical potential. When you read "setting its potential to zero" what is really meant is "setting its Voltage (its potential difference) to zero with respect to the Earth".

How can there be electric potential with zero electric field in one?

The same is the case for electrical potential energies. You could place a positive charge at the shown equipotential line and say that zero (electrical) potential energy is stored. Then surely, the charge will want to move towards the neighbour locations where the potential energy stored is less than zero. That somebody chose the potential energy values at this particular equipotential line to be zero, doesn't matter.

When electric field zero?

Gauss law states that the total electric flux through a hypothetical closed surface is always equal to (1/ε0) times the net charge enclosed by the surface. The electric flux is nothing but the rate of flow electric field through the given area. Since the electric charges are not present inside the conductors, the electric field will remain zero.

Does zero electric flux imply zero electric field?

No. Flux is only the electric field component normal to some surface. Zero flux might just mean the electric field is parallel to the surface.
