resistivity and resistance are two diff. things...........resistance depends on length and thickness resisitivity too depends on the area and length resistivity=resistance*area/length

What does resistance in wire depend on?
Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area. As resistivity is affected by temperature, we can say that temperature indirectly affects resistance.
How many dimensions can an array be created in c?
There is no language limit to "How many dimensions can an array be created in c?". The limit will depend on available memory.
What does a insulator and a conductor mean?
An insulator is a material that prevents the passage of electricity. An example is the plastic insulating cover on electrical wires, A conductor is a material that allows electricity to flow. An example is the copper wire used inside electrical cables.
What is the ductility of mild steel?
The thermal conductivity of steel varies depending on the alloy. (It also varies as the temperature of the metal.) Stainless steels are generally only about a third as thermally conductive as carbon steel. Copper is about ten times as thermally conductive as carbon steel. If a "number" is somehow required for the thermal conductivity (k) of steel, try k = 40 W/m K (at about 25 oC).
Does resistance depend upon current?
The higher the resistance the lower the current flow. It restricts the flow of electrical current. The resistance will not depend upon the current. The current flow will depend on the resistance.
What change in resistivity if length is doubled?
Resistivity is a property of a substance, and doesn't depend on the dimensions of a sample. If the length of a conductor is doubled, then its resistance doubles but its resistivity doesn't change.
Is resistivity of a material depends upon the dimensions of a material?
No. Resistivity is a property of the material itself and does not change no matter how much of that material you have. Resistance, however, does depend on the dimensions of the material.
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.
Does electrical resistance depend on temperature and bias voltage?
Electrical resistance depends on the temperature but not the biased voltage.AnswerIt's resistivity that can be affected by temperature, which means that resistance is indirectly affected by temperature.
What does resistance in wire depend on?
Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area. As resistivity is affected by temperature, we can say that temperature indirectly affects resistance.
If the diameter of wire is double what is resestivity?
Resistivity won't change. Resistivity is a material property that doesn't depend on the shape.
Do resistivity depend upon area of crosss-section?
No. Resistance does.
Does resistivity depend on length and area of the cross section of the material?
No. Resistivity is a material constant, defined for a standard size of material. For another size of material, it can be calculated. Resistivity is the same for any piece of material; resistance can change.
What is the volume of the bar?
The answer will depend on its dimensions.
Difference between resistance and resistivity?
Nothing. Resistivity is defined as specific resistance. However, Resistivity is different from resistance.Answer:Resistance is the opposition offered by the material which is of any shape and size whereas resistivity is the resistance offered by the material with unit area of cross section and unit length.Therefore, resistance varies depending upon shape and size of the material while resistivity is constant for a particular material.
