Electric resistivity measures the ability of a material to resist the flow of an electric current through it. It is an intrinsic property of a material and is dependent on factors such as the material's composition and temperature. Resistivity is typically measured in ohm-meters.
What else can I help you with?
Is resistivity vector or scalar?
Resistivity is a scalar quantity. It is a measure of how strongly a material opposes the flow of electric current through it.
What is resistivity on what factor is depends?
Resistivity is a measure of a material's ability to resist the flow of electric current. It depends on factors such as the material's composition, temperature, and dimensions. Materials with high resistivity impede the flow of current more than those with low resistivity.
What is resistivity and what factor does it depend?
Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is theohm⋅metre (Ω⋅m)It defined as resistance offerde by a unit length and cross section area conductor.It depends on material used.it depends on relexation time and temperature.
What is the Difference between reluctance and resistivity?
Resistivity is the intrinsic property of a conductor, and it is independent of the size of that conductor. Resistance is an extrinsic property that makes it dependent upon the amount of the material that there is present.
What is volume resistivity?
Volume resistivity is a measure of a material's ability to resist the flow of electric current through its volume. It quantifies how well a material can insulate against the passage of electrical current and is expressed in ohm-meters (Ω∙m). Materials with high volume resistivity are good electrical insulators.

Does high resistivity have a higher number or lower number?
High resistivity corresponds to a higher numerical value. In the context of materials, resistivity is a measure of how strongly a material opposes the flow of electric current; materials with high resistivity, like rubber or glass, have larger resistivity values compared to conductive materials like copper or aluminum, which have low resistivity values.

How are materials classified on the basis of resistivity?
Materials can be classified based on their resistivity as conductors, semiconductors, or insulators. Conductors have low resistivity, allowing electric current to flow easily. Semiconductors have resistivity in between conductors and insulators, and their conductivity can be controlled. Insulators have high resistivity and do not allow electric current to flow easily.
Is electrical resistance and electrical resistivity the same?
No, they are not the same. Electrical resistance is a measure of how much a material opposes the flow of electric current, while resistivity is a property of the material itself that determines its resistance. Resistivity is an intrinsic property of the material, while resistance depends on the dimensions and shape of the material.
How can one accurately measure water resistivity?
One can accurately measure water resistivity by using a device called a conductivity meter. This device measures the ability of water to conduct electricity, which is directly related to its resistivity. By measuring the electrical conductivity of water, one can determine its resistivity accurately.
How are substances classified on the basis of resistivity?
Substances are classified based on their resistivity as conductors, insulators, or semiconductors. Conductors have low resistivity and easily allow the flow of electric current. Insulators have high resistivity and inhibit the flow of electric current. Semiconductors have resistivity values between conductors and insulators, making them suitable for controlling the flow of current in electronic devices.
Why do some materials have more resistance than others?
Materials with more resistance have a higher resistivity, which is a measure of how strongly a material impedes the flow of electric current. Factors such as the material's atomic structure, temperature, and impurities can affect its resistivity. Materials like metals tend to have low resistivity due to their abundance of free electrons, while insulating materials have higher resistivity as they inhibit the movement of electrons.
Can resistivity be negetive?
No, resistivity cannot be negative. Resistivity is a material property that indicates how strongly a material opposes the flow of electric current. It is always a positive quantity, even though some materials may have very low resistivity values.
