If we place a charged body to a position it feel a force which depends the presence of other charged body around it. Now we can say something was there in that position before placing that charged body. Here arise a concept of electric field.Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge. A simple isolated electron in an earth can create an electric field in the moon eventhough its negligible.

On a map for example you see lines which show uniform height and you can deduce gradients and hence find hills. Electric field lines show the same thing but instead of height of the ground it shows intensity of the field.

They don't affect the charge that created them.
They never cross.

Which of the following is true about the electric field around an electric charge?
The electric field around an electric charge varies inversely as the square of the distance to the charge.
Which of the following are created by an arrangement of electric charge or a current?
for apex its: a quantum field, a gravitational field
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.
Gets stronger as you get closer to an electric charge?
The electric field gets stronger as you get closer to an electric charge.
Why electric field lines cannot have sudden brakes in between them?
electric field lines represents electric field at that point but if it has break somewhere then it signifies the absence of electric field and it is not possible.....
What factors are involved in electric field?
there are two factors in electric field which are responceable to describe the electric field.that is E and D.

Describe an electric field?
The electric field is defined as the force per unit positive charge that would be experienced by a stationary point charge at a given location in the field.
Which of the following correctly describe magnetic field line?
APEX: Field lines that are close together indicate a stronger magnetic field. They don't affect the magnet that created them. They never cross. They begin on north poles and end on south poles.
Is an electric field?
The electric field is something that exists throughout all space, and only charges can interact with it.The electric field is something used to help describe 'action at a distance'.Imagine two charges separate from each other, both charges experience a force, however they are not touching. The electric field is needed to describe why they experience a force.The electric field strength is defined as the force experienced per charge Q, sitting in that field.E=F/QThe electric flux can be seen much like a flux of water.Here the flux (flow) of water is the amount of water passing through an area.Just as with water, the electric flux is the amount of electric field passing through an area.The stronger the electric field - the higher the flux, per unit area.Imagine flux as a flow of the electric field.Flux = E*A
Why is the electric field is a vector?
Because to completely describe it you must know both how strong it is (magnitude) and in what direction it points.
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.
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.

Can an electric field exist without a magnetic field?
An electric field can exist even without the presence of a magnetic field. An example of this is a stationary electric field.
Gets stronger as you get closer to an electric charge?
The electric field gets stronger as you get closer to an electric charge.
What is the area around an electric charge which is strongest closest to the charged particle?
It's the electric field.
