What is electric conductivity intensive or extensive?
Electric conductivity is an intensive property because it does not depend on the size or amount of the material being measured. It is a characteristic of the material itself, not influenced by the quantity.
The ability of a material to transfer heat or electric current is call what?
The ability of a material to transfer heat is called thermal conductivity, while the ability to transfer an electric current is known as electrical conductivity.
What controls the flow of current with an electric field?
The flow of current in a material is controlled by its conductivity, which is influenced by the presence of an electric field. When an electric field is applied, it can cause charged particles in the material to move, resulting in the flow of current. The conductivity of the material determines how easily current can flow in response to the electric field.
What is a material that conducts electric current?
Material with high resistance
What is thermal conductivity for fiber glass insulation?
The thermal conductivity of fiberglass insulation typically ranges from 0.2 to 0.4 W/m-K. This means that fiberglass insulation is an effective material for reducing heat transfer through walls, floors, and ceilings in buildings.

What is longitudnal conductivity?
Longitudinal conductivity refers to the ability of a material to conduct electric current along its length or in the same direction as an applied electric field. It is typically associated with the flow of charge carriers through a material. Materials with high longitudinal conductivity are good conductors of electricity.
Is styrofoam a good insulation?
Styrofoam is a very porous material; air from the closed pores has a bad thermal conductivity.
What is the nickname for electrical conductivity?
The nickname for electrical conductivity is "conductance." It refers to the ability of a material to allow the flow of electric current through it.
How do builders describe the insulation ability of a material?
Usually it's the conductivity of a material that is given, measured in Watts per square metre. The more conductive, the lower the insulation. If a wall or material has a low conductivity, then is is a good insulator. It's a measure of how much heat energy the material will pass.
What is electical conductivity?
Electrical conductivity is a measure of a material's ability to conduct an electric current. It is determined by the availability of free electrons in the material that can move in response to an applied electric field. Materials with high electrical conductivity, like metals, allow electric current to flow easily, while insulators have low conductivity and impede the flow of current.
What material conducts electric current better than an insulation but not as well as a conductor?
semiconductor
What is DC conductivity?
Direct current (DC) is the unidirectional flow of electric charge."Conductivity" is just the ability of a substance to conduct electric current.Copper and silver have a lot of conductivity. Glass has very little of it.
