an electric charge seas up an electric field in it's surroundings.it exerts force upon any charges which arrives in this field region.the force will be stronger when the field intensity is higher
The electric field intensity at a point is the force experienced by a one coulomb positive charge placed at that point. If suppose 5 C charge experiences a force of 20 N then 20/5 = 4 N/C will be the field intensity
That could also be sensed as the number of electric (imaginary) lines of force crossing at right anles for unit area. Here no need to bring unit area. Just 0.0000001 sq m is enough. If suppose 3 lines pass through this then for unit area we can calculate by dividing 3/ 0.0000001
So it would be 30000000 N/C
Quite simply, the more field lines per unit area, the greater the field density. More field lines equates to a greater field intensity. It's that simple.
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.....
1. Electric field lines of force originate from the positive charge and terminate at the negative charge. 2. Electric field lines of force can never intersect each other. 3. Electric field lines of force are not present inside the conductor, it is because electric field inside the conductor is always zero. 4. Electric field lines of force are always perpendicular to the surface of conductor. 5. Curved electric field lines are always non-uniform in nature.
electric lines of force are imaginary lines defined by the paths traced by unit charges placed in an electric field. Lines of force are everywhere parallel to the electric field strength vector. Their principal use is as a convenient means of picturing the geometry of an electric field.
No, they only help us understand electric fields.
No, if two electric field lines are drawn at a point, this would meant two directions of electric field at that point which is impossible.
Under an electric field, magnitude and direction of electric intensity is different in every point.If the electric intensity can be defined through a closed line (direction of electric intensity will be along the tangent of any point of that line)this is called electric lines of force. Electric lines of forces passing through an closed electric surface perpendicularly, is called electric flux.
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.

The lines in each diagram represent an electric field. The stronger the field, the close together the lines are.
To reduce the electric field intensity at the surface of the conductor which can lead to corona discharge and insulation breakdown. By using bundled conductors, the electric field is distributed between the four (in the case of 400-kV lines) conductors, thus reducing the field intensity per conductor.

No, if two electric field lines are drawn at a point, this would meant two directions of electric field at that point which is impossible.
An electric field has both magnitude and direction and can be represented by lines of force, or field lines, that start on positive charges and terminate on negative charges.
The electric field lines are directed away from a positive charge and towards a negative charge so that at any point , the tangent to a field line gives the direction of electric field at that point.
