There are two answers to your question, and they depend on whether we're talking about electrostatics or electrodynamics.
Electrostatics:No. In the absence of a varying magnetic field, the electric field intensity is equal to just the negative gradient of the electric potential; E = -∇Φ. So, if Φ is 0, its gradient, which is just the vector field made from the partial derivatives of Φ, has to be 0. The reverse, however, can happen. E can be 0, but Φ doesn't have to be; it can also be a non-zero constant. Electrodynamics:Yes. In the presence of a varying magnetic field, E = -∇Φ - ∂A/∂t, where A is the magnetic vector potential, and t is time. So, if Φ is 0 this time, E can still be equal to the possible non-zero term, -∂A/∂t.Wiki User

Yes, it is possible for the electric intensity to be zero at a point while the electric potential is not zero. This can occur when the electric field lines are parallel to equipotential surfaces, causing the electric field to be tangent to the surface, resulting in zero electric field intensity but a non-zero potential difference.

What is the electric field intensity at the mid point of dipole?
The electric field intensity at the midpoint of a dipole is zero. This is because the electric fields created by the positive and negative charges of the dipole cancel each other out at that point, resulting in a net electric field intensity of zero.
What unit of Electric Intensity is?
The unit of electric intensity is volts per meter (V/m). Electric intensity represents the electric field strength at a specific point in space and is measured in terms of volts per meter.
What is the electric potential at a point in space if a charge of 7.3 10-17 coulombs at that point has a potential energy of 6.4 10-17 joules?
The electric potential at a point in space is the electric potential energy per unit charge, so you can calculate it by dividing the potential energy by the charge at that point. In this case, the electric potential at the point would be 6.4x10^-17 J / 7.3x10^-17 C = 0.876 V.
What is the voltage at the location of a Coulomb charge that has an electric potential?
The voltage at the location of a Coulomb charge with an electric potential is the work required to move a unit positive charge from a reference point to that location. It is a measure of the potential energy per unit charge at that point in the electric field.
Is a electric potential scalar or vector?
Electric potential is a scalar.
What distinguish electric field intensity from electric potential stating the unit of each?
Electric field intensity (E) measures the force experienced by a charged object in an electric field, while electric potential (V) represents the potential energy per unit charge at a specific point in the field. The unit of electric field intensity is volts per meter (V/m), and the unit of electric potential is volts (V).
Do electrons move up or down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field

Why you take point at infinity in describing electric potential?
The point at infinity is often used in discussing electric potential as a reference point to define the zero level of potential energy. This helps in calculating the potential difference between different points in the electric field. By setting the potential at infinity to zero, it allows for a consistent and convenient way to describe electric potential.
Do electron moves up or fall down a potential gradient?
The potential gradient gives the electric field intensity E at point in electric field which is directed from high to low potential. An electron being a negative charge particle therefore will tend to move from low potential to high potential, hence will move up the electric field

What is the voltage between point p and the battery?
The voltage between point p and the battery is not able to measured exactly. You can never measure the absolute electric potential at any point. its just not possible. That is why we talk about difference in potential.
What is the voltage at the location of a Coulomb charge that has an electric potential?
The voltage at the location of a Coulomb charge with an electric potential is the work required to move a unit positive charge from a reference point to that location. It is a measure of the potential energy per unit charge at that point in the electric field.
Is a electric potential scalar or vector?
Electric potential is a scalar.
What are factors that determine the size of the electric potential and electric potential energy?
The size of the electric potential is determined by the amount of charge creating the electric field and the distance from the charge. The electric potential energy depends on the charge of the object and its position in the electric field, as well as the electric potential at that point.
Can two different equipotential lines cross each other?
No, two different equipotential lines cannot cross each other. Equipotential lines are points in a space at which the electric potential has the same value. If two equipotential lines were to cross, it would mean that the electric potential at that point has two different values, which is not possible according to the definition of equipotential lines.
