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.

- Electric field lines show the direction of the force on a positive test charge in an electric field.
- Electric field lines originate from positive charges and terminate on negative charges.
- The density of field lines indicates the strength of the electric field, with closer lines representing stronger fields.
- Electric field lines never cross each other in a region of space.

∙ 14y agoElectric field lines show lines of uniform strength of the electric field.
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 is a vector field that exerts a force on other charges placed in the field. The strength of the electric field decreases with distance from the charge following the inverse square law. The direction of the electric field is radially outward from a positive charge and radially inward toward a negative 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
What is a radial electric field?
A radial electric field refers to an electric field oriented radially outward or inward from a central point or line. In the context of physics or engineering, it is often used to describe the electric field configuration in certain systems or devices, such as electric motors or charged particles moving along a radial path.
What is electric displacement?
Electric displacement (D) is a concept used in electromagnetism to describe the electric field inside a material. It takes into account the effects of both free and bound charge distributions. It is related to the electric field inside a material through the equation D = εE, where ε is the permittivity of the material and E is the electric field.
What most affect the strength of an electric field?
distance between charged particles.
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.

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
What influences the strength of an electric field?
The strength of an electric field is influenced by the magnitude of the charge creating the field and the distance from the charge. The field strength decreases with distance from the charge following the inverse square law. Additionally, the medium through which the field is propagating can also affect its strength.
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.
What is meant by electric field intencity?
Electric field intensity represents the strength of an electric field at a specific point. It is a vector quantity that indicates the force experienced by a positive test charge placed at that point. The magnitude of the electric field intensity is given by the force per unit charge.
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.
How do you compare and contrast the electrical field around a negative charge and the electric field around a positive charge?
The electric field around a negative charge points inward, towards the charge, while the electric field around a positive charge points outward, away from the charge. The electric field strength decreases with distance from both charges, following an inverse square law relationship.
