Top best answers to the question «What is the electric field at a location»
- The electric field at a location indicates the force that would act on a unit positive test charge if placed at that location. The dimensions of electric field are newtons/coulomb, . For a positive , the electric field vector points in the same direction as the force vector. The equation for electric field is similar to Coulomb's Law.

Electric Field: A force will work on the charge if it is present within the region of an electric field. This force causes the motion of that charge. Its movement depends on the direction of the ...
The electric field is radially outward from the point charge in all directions. The circles represent spherical equipotential surfaces. The circles represent spherical equipotential surfaces. Notice the r in the denominator.
Electric field is defined as the ratio of force to charge at a given point in space. The force on a charge can only point in one direction and so does the electric field. Therefore, the field lines never cross, since that would indicate two different directions at the crossing point.
Electric field strength is also known as electric field intensity and is an expression of the intensity of an electric field at a particular location. One may also ask, what is electric field formula? E = kQ / r 2. Where r is a unit vector of the distance r with respect to the origin. This value E(r) [SI unit N/C] amounts to an electric field of each charge based on its
In fair weather, the electric field in the air at a particular location immediately above the Earth's surface is 120 N / C directed downward.
This expression is called the electric field at position P = P(x, y, z) of the N source charges. Here, P is the location of the point in space where you are calculating the field and is relative to the positions →ri of the source charges (Figure 5.5.1). Note that we have to impose a coordinate system to solve actual problems.
