The electric field is a region of space surrounding an electric charge in which other charges experience a force. The electric field is a vector field, which means it has both a magnitude and a direction. The direction of the electric field at any point is the direction in which a positive test charge would experience a force if it were placed at that point.

The electric intensity, also known as the electric field strength, is the magnitude of the electric field at a point. It is a measure of the force per unit charge that would be experienced by a positive test charge placed at that point. The unit of electric intensity is the newton per coulomb (N/C).

The direction of the electric intensity is the same as the direction of the electric field. A positive test charge will experience a force in the direction of the electric field, while a negative test charge will experience a force in the opposite direction.

The electric field is strongest near the source charge and decreases as the distance from the source charge increases. The electric field is zero at a point where the net charge is zero.

The electric field can be represented by a set of arrows, each of which has a magnitude and a direction that corresponds to the magnitude and direction of the electric field vector at that point. The arrows are drawn so that they point in the direction of the force that would be exerted on a positive test charge placed at that point.

Here are some examples of electric fields:

* The electric field around a positive charge points away from the charge.
* The electric field around a negative charge points towards the charge.
* The electric field between two oppositely charged plates points from the positive plate to the negative plate.
* The electric field around a conducting wire carrying a current points in the direction of the current.
