How are equipotentials lines oriented with respect to electric field lines?
Equipotential lines are always perpendicular to electric field lines. This is because equipotential lines represent points in a field with the same electric potential, so moving along an equipotential line does not change potential. Thus, the electric field lines, which point in the direction of the greatest change in potential, intersect equipotential lines at right angles.
What is the relationship between the density of the equipotential lines and the strength of the electric field in a given region?
The density of equipotential lines is inversely proportional to the strength of the electric field in a given region. This means that where the equipotential lines are closer together, the electric field is stronger, and where they are farther apart, the electric field is weaker.
Why are equipotential lines perpendicular to the insulator mapped?
Equipotential lines are perpendicular to the insulator surface because the electric field lines are always perpendicular to the equipotential lines in electrostatic equilibrium. This relationship ensures that there is no component of the electric field tangent to the insulator surface, which would cause the charges to move. As a result, the charges remain at rest on the surface of the insulator.
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.
What best describes an equipotential surface and its significance in the context of electric fields?
An equipotential surface is a surface where all points have the same electric potential. In the context of electric fields, it signifies that no work is required to move a charge along that surface, as the electric field is perpendicular to the surface. This helps in visualizing the electric field lines and understanding the distribution of electric potential in a given region.

What instrument measures the electric equipotential?
Multimeter is an instrument that measures electric equipotential. Equipotential lines can be determined by connecting various points of electric potential or voltage.
What are equipotential lines?
A uniform electric field exists between parallel plates of equal but opposite charges.
Why must electric field line be perpendicular to equipotential surfaces?
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.

Why are the equipotential lines near conductor surfaces parallel to the surface?
For conductors, the electric field perpendicular to its surface and no field exist within the conductor. As a result the equipotential lines are found near the surface. They are parallel to the surface since equipotential are perpendicular to field lines.
What is the angle between lines of force and equipotential lines in an electrical field?
The angle is a right angle.
If the electric potential is zero, what is the relationship between the electric field and the potential at that point?
If the electric potential is zero, the electric field at that point is perpendicular to the equipotential surface.
Why aconductor is an equipotential surface?
A conductor is an equipotential surface because the electric field inside a conductor is zero in electrostatic equilibrium. This means that all points on the conductor have the same electric potential, making it an equipotential surface. Any excess charge on the conductor redistributes itself to ensure this equal potential.
