What is Dielectric Strength?

Back

The strength of an electric field necessary to cause significant electric flow through a dielectric material.

Front

What is Flexural Strength?

Back

Applied stress at the time of fracture from a test in which stress is perpendicular to the axis of deformation, generally used to characterize beams.

Front

What is Resistivity?

Back

The reciprocal of electrical conductivity, measuring the resistance to the flow of electric current.

Front

What is Passivity?

Back

The loss of chemical reactivity by some active metals and alloys, often due to the formation of a thin oxide surface coating.

Front

What is the difference between Microstructure and Macrostructure?

Back

Microstructure refers to the small-scale features of a material, while Macrostructure refers to the larger, overall structure.

Front

What is the significance of grain boundaries in materials?

Back

Grain boundaries can affect the mechanical properties of materials, such as strength and ductility.

How does temperature affect the dielectric strength of materials?

Back

Generally, as temperature increases, the dielectric strength of materials decreases.

What is the relationship between tensile strength and flexural strength?

Back

Tensile strength measures resistance to being pulled apart, while flexural strength measures resistance to bending.

Front

What is the role of oxide coatings in passivity?

Back

Oxide coatings can protect metals from further chemical reactions, enhancing their durability.
