What is electric lines of force?
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.
How are the field lines related to the intensity of an electric field?
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
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.
Electric field is positive or negative?
Did you mean "The strength of electric field is positive or negative"? Anyway, there is your answer.. The strength of an electric field E at any point is defined as the electric force F exerted per unit positive electric charge q at that point, or E = F/q.You can say that it is positive.
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 the electric field and force is same for unit charge?
The numbers will be the same, because electric field is defined as "force per unit charge". The units, however, will not be the same.
What is the 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.
What does newtons divided by coulombs equal?
That's the unit for the electric field. The SI units for electric field are, precisely, newtons/coulomb - or the equivalent, volts/meter. This unit doesn't have a special name.
Definition to 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.
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.

What is is true about electric field around an electric charge?
Everything. A positive charged particle generates an electric field equivalent to the work done in bringing a unit positive charge from infinity to near that charge.
Unit for expressing strength of electric field?
Neuton per coulomb(N/C)
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.
