An Electric field stress depends on the mechanical strength of the materials and the stresses that are generated during their operation. During high voltage applications, the dielectric strength of insulating materials are developed when subjected to high voltages.

What is dielectric stress?
The dielectric stress is the stress placed upon a material when a voltage is placed across it.
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
What is a not a part of an electric motor?
A field of wheat
What is dielectric stress?
The dielectric stress is the stress placed upon a material when a voltage is placed across it.
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.
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 the area around an electric charge which is strongest closest to the charged particle?
It's the electric field.
Can an electric field exist without a magnetic field?
Yes, an electric field can exist without a magnetic field. Electric fields are produced by electric charges, while magnetic fields are produced by moving electric charges. So, in situations where there are stationary charges or no current flow, only an electric field is present.
Why electric field lines cannot have sudden brakes in between them?
Electric field lines represent the direction of the electric field at any point in space. If there were sudden breaks in the field lines, it would imply sudden changes in the electric field strength, which is not physically possible. The electric field must vary continuously and smoothly in space.
What is relation between electric field intensity and electric potential?
Electric field intensity is related to electric potential by the equation E = -∇V, where E is the electric field intensity and V is the electric potential. This means that the electric field points in the direction of steepest decrease of the electric potential. In other words, the electric field intensity is the negative gradient of the electric potential.
Why electric line of force can not have sudden break?
Electric field lines represent the continuous flow of electric field from one point to another. If there were a sudden break in the electric field line, it would imply a sudden discontinuity in the electric field strength, which is not physically possible. This is because electric field lines are a visual representation of the direction and strength of the electric field, which must be continuous to maintain the conservation of electric field flux.
How closely packed the electric field lines are indicates the strength of the electric field?
true
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.
Relationship between electric field intensity and electric potential?
Electric field intensity is related to electric potential by the equation E = -dV/dx, where E is the electric field intensity, V is the electric potential, and x is the distance in the direction of the field. Essentially, the electric field points in the direction of decreasing potential, and the magnitude of the field is related to the rate at which the potential changes.
What is the velocity experienced by an electron in an electric field?
The velocity experienced by an electron in an electric field depends on the strength of the field and the mass of the electron. The velocity will increase as the electric field strength increases. The electron will accelerate in the direction of the electric field.
