How closely packed the electric field lines are indicates the strength of the electric field?
true
Is electric field scalar or vector?
The strength of the electric field is a scalar quantity. But it's the magnitude of thecomplete electric field vector.At any point in space, the electric field vector is the strength of the force, and thedirection in which it points, that would be felt by a tiny positive charge located there.
What equation is used to describe the electric strength at a point in space?
The electric field at a point in space is the magnitude and direction of the force that would act on a small test charge if it were located at that point.
Does electric field and electric field lines connected?
Yes. An electric field is represented by electric field lines. Electric field lines are a visual representation of the strength and direction of an electric field in a region of space. In the vicinity of any charge, there is an electric field and the strength of the electric field is proportional to the force that a test charge would experience if placed at the point. (That is a matter of definition of electric field.) Mother nature produces electric fields, but humans can not see electric fields. Humans invented the idea of field lines to create a mental picture of the field. The two most common ways are to draw lines in space or to draw a collection of arrows in space. In the case of arrows, they are vector representations of the strength and direction of the electric field at the point in space where each arrow is drawn. Representing an electric field (and this works with other fields also) with lines is a sophisticated and time honored tradition. The density of lines in any region of space is proportional to the strength (magnitude) of the field in that region of space. The direction of the field is along the direction of the line at each position on each of the lines. In such a graphical representation the field direction goes out from positive charge and in towards negative charge and the visualization usually has some indication of the sign of charge or direction of the field to give the information about direction of the vector field represented by the field lines. There is a small caveat. It is not only charge that can produce electric fields. An electric field can be produced by a changing magnetic field. This is technologically important (since electric motors work on this principle) and scientifically fascinating, requiring a somewhat more sophisticated aspect of electromagnetic theory, but ultimately the electric field or electric flux can be visualized with lines (or arrows) in a manner exactly as is done for stationary charges.

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.
Can electric field lines intersect in free space?
No, because the electric field would not be defined at the intersection point.

What is meant by electric field intencity?
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 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 the definition of the term dielectric?
'Dielectric' is often used in a general sense to refer to a material (such as ceramic, mica, plastic or paper) which is a poor conductor of electricity. This term is used in the classical description of a capacitor -- two electric conductors separated by a dielectric. By applying electric charge to one conductor an electric field is created. The dielectric allows the electric field to pass through it and affect the other conductors; however the dielectric prevents electrons from flowing between the conductors, so the electric field remains (and the charge remains stored on the conductor). [Side note for beginners: An electric field creates a force (measured in Volts) upon an electron or charged particle which tends to make it move. The conductor allows electrons to move easily within it. The dielectric resists the movement of electrons in it.] More generally, we speak of a 'Dielectric Field' as a mathematic description of how electric charge influences the properties of the space around it. The Dielectric field interacts with space and with any material in the space to create an 'Electric Field'. In simple terms, the electric field at any point is the product of the dielectric field at that point and the 'Dielectric Constant' of the material at that point. In more general terms, the 'electric field vector' at a point is the tensor product of the 'dielectric field vector' and the 'dielectric tensor' of the material at that point. The dielectric field is not a measurable entity, but rather a mathematical tool that allows us accurately to model the electric field, which is measurable. The article on Dielectrics at http://en.wikipedia.org/wiki/Dielectric provides more description, especially on the dielectric field model.
