An electric field can be represented diagrammatically as a set of lines with arrows on, called electric field-lines, which fill space. Electric field-lines are drawn according to the following rules: The direction of the electric field is everywhere tangent to the field-lines, in the sense of the arrows on the lines. The magnitude of the field is proportional to the number of field-lines per unit area passing through a small surface normal to the lines. Thus, field-lines determine the magnitude, as well as the direction, of the electric field. In particular, the field is strong at points where the field-lines are closely spaced, and weak at points where they are far apart. Electric Field intensity It was stated that the electric field concept arose in an effort to explain action-at-a-distance forces. All charged objects create an electric field which extends outward into the space which surrounds it. The charge alters that space, causing any other charged object that enters the space to be affected by this field. The strength of the electric field is dependent upon how charged the object creating the field is and upon the distance of separation from the charged object. In this section of Lesson 4, we will investigate electric field from a numerical viewpoint - the electric field strength.

What else can I help you with?
Can an electric field exist without a magnetic field?
Yes, an electric field can exist without a magnetic field. Electric fields are produced by electric charges, while magnetic fields are produced by moving electric charges. So, in situations where there are stationary charges or no current flow, only an electric field is present.
What is a magnetic field will be produced at some point in space if the electric field at the point?
As far as the electric field is stationary then no magnetic field. But when electric field is moving at a uniform speed then a magnetic field will be produced. This is what we call Lorentz magnetic field.
An electric field surrounds an electric charge What additional field surrounds a moving electric charge?
A moving electric charge produces both an electric field and a magnetic field. The magnetic field surrounds the moving charge and is perpendicular to both the direction of motion and the electric field. This combined electromagnetic field is described by Maxwell's equations.
Is electric field dependent of magnitude of charge?
Yes, the electric field created by a point charge is directly proportional to the magnitude of the charge. As the charge increases, the electric field strength at a given distance from the charge also increases.
An electric dipole is placed in a nonuniform electric filedIs there a net force on the dipole?
yes, there is a NET field .electric dipole experiences a net field .(not in uniform E.Field)
Can two electric field lines be drawn at a point?
No, two electric field lines cannot originate from the same point because the electric field direction at that point would be ambiguous. Electric field lines always point in the direction of the electric field at a given point and represent the direction a positive test charge would move in that field.
What is meant by electric field between the plates?
ELECTRIC FIELD The electric of a charge is the region of space surrounding in which a point charge can experience its influence in the form of a force The regon around any charged body in which coloumb's force is experienced by some other charged body is called "electric field" of the first body.
What is meant by total normal electric induction over a surface?
Total normal electric induction over a surface refers to the total electric flux passing through the surface when the electric field is perpendicular to the surface. It is a measure of the total electric field passing through the surface and is calculated by the dot product of the electric field and the surface area vector.
What is intencity of light?
It is luminous intensity measured in candelas
Why does the electric field inside a dielectric decrease when it is placed in an external electric field?
The net electric field inside a dielectric decreases due to polarization. The external electric field polarizes the dielectric and an electric field is produced due to this polarization. This internal electric field will be opposite to the external electric field and therefore the net electric field inside the dielectric will be less.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
What is the relationship between the electric field equation and voltage in an electric field?
The electric field equation describes the strength and direction of the electric field at a point in space. Voltage, on the other hand, is a measure of the electric potential difference between two points in an electric field. The relationship between the electric field equation and voltage is that the electric field is related to the gradient of the voltage. In other words, the electric field is the negative gradient of the voltage.
What is the area around an electric charge which is strongest closest to the charged particle?
It's the electric field.
Is voltage the derivative of electric field?
No, voltage is not the derivative of electric field. Voltage is a measure of electric potential difference, while electric field is a measure of the force experienced by a charged particle in an electric field.
Can an electric field exist without a magnetic field?
Yes, an electric field can exist without a magnetic field. Electric fields are produced by electric charges, while magnetic fields are produced by moving electric charges. So, in situations where there are stationary charges or no current flow, only an electric field is present.
What is the amplitude of the associated electric field?
The amplitude of the associated electric field refers to the maximum strength or intensity of the electric field. It represents the peak value of the electric field's magnitude.
What is relation between electric field intensity and electric potential?
Electric field intensity is related to electric potential by the equation E = -∇V, where E is the electric field intensity and V is the electric potential. This means that the electric field points in the direction of steepest decrease of the electric potential. In other words, the electric field intensity is the negative gradient of the electric potential.
