What else can I help you with?
What do lines represent in an electirc field diagram?
The lines in each diagram represent an electric field. The stronger the field, the close together the lines are.
What are the difference between elactric field and electric displacement field?
The electric displacement field is a vector field, shown as D in equations and is equivalent to flux density. The electric field is shown as E in physics equations.
What device uses motion in an electric field to produce an electric current?
electric genarator
For a parallel plate capacitor is The poynting vector points everywhere radially outward of the volume between plates?
No, the Poynting vector does not point radially outward in the volume between the plates of a parallel plate capacitor. The Poynting vector represents the direction and flow of electromagnetic energy, and in the case of a static electric field between the plates, the Poynting vector is zero within the volume between the plates.
Does the voltage between two points in a circuit decrease or increase when the electric field in the circuit increase?
When the electric field in a circuit increases, the voltage between two points typically increases as well. This is because voltage is directly related to the electric field and the distance between the points, following the relationship ( V = E \cdot d ), where ( V ) is voltage, ( E ) is the electric field strength, and ( d ) is the distance. Thus, an increase in the electric field generally results in a higher voltage across the same distance.
How many lines of forces would radiate outward from one coulomb of charge in vacuum?
In a vacuum, the number of lines of force radiating outward from one coulomb of charge is infinite. This concept is based on the inverse square law, where the electric field strength decreases as the square of the distance from the charge.
Do electric fields point outward or inward?
Electric fields point outward from positive charges and inward toward negative charges. This direction represents the direction of the force that a positive test charge placed in the field would experience.
How do the electric field lines around a positive charge look?
They look like the spokes on a 3D wheel, the stickers on a spherical cactus, or thequills on a scared porcupine. Every field line is a straight line pointing directly awayfrom the positive charge.
What is the distribution of the electric field inside an insulating cylinder?
The electric field inside an insulating cylinder is uniform and radial, meaning it points outward from the center of the cylinder in all directions.
What is the electric field due to a line of charge?
The electric field due to a line of charge is a vector field that points radially outward from the line of charge. Its magnitude decreases as the distance from the line of charge increases.
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 the electric field of a uniformly charged sphere?
The electric field of a uniformly charged sphere is the same as that of a point charge located at the center of the sphere. This means that the electric field is radially outward from the center of the sphere and its magnitude decreases as you move away from the center.
What is the electric field around a very long uniformly charged cylinder?
The electric field around a very long uniformly charged cylinder is uniform and points radially outward from the cylinder.
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.
How do you make an electric field?
An electric field is created by a charged object. The field extends outward from the object in all directions and its strength decreases with distance. The electric field is a fundamental concept in physics that helps explain the interactions between charged particles.
In which direction is the electric field on the cylindrical Gaussian surface oriented?
The electric field on the cylindrical Gaussian surface is oriented perpendicular to the surface, pointing outward or inward depending on the charge distribution inside the surface.
This exerts a force on anything that has an electrical charge?
An electric field has what are called lines of force that radiate outward from the electric charge that creates them. It is the "touch" or the interaction with these lines of force that allow an electric field to exert a force (an electrostatic force) on anything with an electric charge.A fundamental law of electrostatics is that like charges repel and opposite charges attract. A charge will have an electric field around it, and if another charge is nearby, the fields of the charges will interact. Like charges will "push" on each other, while opposite charges will "pull" on each other. It's the fields of the respective charges that interact to cause the effects we see.All electric charges have associated electric fields around them. It is possible to "see" the electric fields like we "see" gravimetric fields. Both forces can "reach across" space to interact with objects at a distance from the source of the force. The field lines (lines of force) carry the force outward and are the means by which interaction occurs.
