Dielectric strength is influenced by material homogeneity because uniform materials tend to have fewer defects, impurities, and inclusions that can serve as initiation points for electrical breakdown. Inhomogeneous materials may exhibit localized weaknesses, leading to lower dielectric strength due to the presence of voids or variations in composition. Thus, a more homogeneous dielectric material generally provides better insulation and higher dielectric strength compared to one that is heterogeneous. Consistent molecular structure and uniformity in a material enhance its ability to withstand electric fields without failure.

What is Electric field stress?
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.
Dielectric constant of insulator depends on?
Frequency of alternating field applied & temperature
Why is steel good in tension?
It depends on its strength. Usually, concrete is 6.7 to 9 times stronger in compression.To be exact, tensile strength of concrete is equal to 0.7 times square root of its compressive strength. For common concretes with compressive strength of 20 to 40 MPa, it is about 3 to 4.4 MPa of tensile strength respectively.
If an item can withstand 300000 PSI of pressure what is its Tensile Strength?
Your question is vague. Any way if it can withstand 300000 PSI the tensile strength is higher than that. It depends on the material since Tensile strength is known as ultimate tensile strength at which level the item fails.
Why does coulomb force between two point charges depends upon dielectric constant of the intervening medium?
It is because when a dielectric is placed between the charges , the dielectric gets polarized and the net electric field between the two charges decreases, hence force = charge x electric field also decreases. john
What is the dielectric breakdown strength?
The dielectric breakdown strength is the maximum electric field that a dielectric material can withstand before it breaks down and allows electrical current to flow through it. It is a measure of the insulation properties of the material.
How a dielectric polarized?
A dielectric material becomes polarized when an external electric field is applied, causing the positive and negative charges within the material to shift in opposite directions. This displacement of charges results in the formation of electric dipoles, which align with the field. The degree of polarization depends on the strength of the electric field and the material's properties, such as its permittivity. Once the external field is removed, most dielectrics return to their original state, though some materials may retain a degree of polarization, known as ferroelectricity.
What is Electric field stress?
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 the impact of a hammerstrike force on a material's durability and strength?
The impact of a hammerstrike force on a material's durability and strength depends on the material's composition and structure. A strong force can potentially weaken or damage the material, reducing its durability and strength. It is important to consider the material's properties and limitations when applying force to avoid compromising its integrity.
What is characteristic strength of steel?
Characteristic Strength is a term used regionally in order to describe the engineering strength of a material. In other words, the Characteristic Strength is the strength of a material (i.e. steel, concrete, etc.) which has been established by a testing and standards body such that, statistically, a defined percentage of material samples, when tested, exhibit strength at or above the characteristic value. This Characteristic Strength is then used by engineers and designers as the material design strength. In the case of steel or other ductile materials which exhibit post-yielding strength, the characteristic strength generally refers to the material elastic response only.
Dielectric constant of insulator depends on?
Frequency of alternating field applied & temperature
What is material constant for a semi conductors?
The material constant for semiconductors is typically represented by the symbol ε (epsilon), and it denotes the relative permittivity or dielectric constant of the semiconductor material. This constant reflects the material's ability to store electrical energy in an electric field and influences properties like capacitance and electric field distribution within the semiconductor device.
Why is steel good in tension?
It depends on its strength. Usually, concrete is 6.7 to 9 times stronger in compression.To be exact, tensile strength of concrete is equal to 0.7 times square root of its compressive strength. For common concretes with compressive strength of 20 to 40 MPa, it is about 3 to 4.4 MPa of tensile strength respectively.
What amount of force is needed to bend tube mital?
It depends on the thickness of the tube, the diameter of the tube and the shear strength of the material.
What does the strength of an electromagnet depend on?
The strength of an electromagnet depends on the current flowing through the coil, the number of turns in the coil, and the magnetic properties of the core material inside the coil. Increasing the current or number of turns will strengthen the electromagnet, while using a high-permeability core material can also enhance its magnetic strength.
How many degrees in a slope would most likely produce a mass movement?
That depends on what the "mass" is made of. The angle of repose depends on the material the slope is made from and the presence (amount) of water in the material. Fs = Shear Strength/Shear Stress
On what factors does the strength of an electroment depends?
The strength of electromagnet depends on the electric current flowing through the core because when the current is stopped, the core is no longer magnetized and the rate of change of flux linkage.
