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
Can an electric field exist without a magnetic field?
An electric field can exist even without the presence of a magnetic field. An example of this is a stationary electric field.
Gets stronger as you get closer to an electric charge?
The electric field gets stronger as you get closer to an electric charge.
What is the area around an electric charge which is strongest closest to the charged particle?
It's the electric field.
Why electric field lines cannot have sudden brakes in between them?
electric field lines represents electric field at that point but if it has break somewhere then it signifies the absence of electric field and it is not possible.....
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.
Can gravitational be added to electric field to get the total field?
No. The sum of the gravitational field and the electric field is a useless concept.
What is a charges electric field?
electric field due to a single charge.
What surrounds electric charges and exerts force on other charges?
An electric field surrounds the charge and exerts force on other charges.
