the electrical resistance of a conductor through unit cross-sectional area per length is called "resistivity of material"
Double the area means half the resistance. Resistance = resistivity times length / area. Resistivity is a property of the material only.
The value for resistivity will remain unchanged (provided temperature remains constant). Resistivity is a property of the material. The resistance, however, will double. Remember that resistance is directly proportianal to the length of the conductor and inversely proportional to the cross-sectional area of the conductor.
Question is not clear.Is question asking about the battery's internal resistance ?AnswerResistance is not affected by voltage. The resistance of a material depends upon the length, cross-sectional area, and resistivity of that material. As resistivity is affected by temperature, resistance is also indirectly affected by temperature.
AnswerThe resistance of a material depends on its length, cross-sectional area, and resistivity. This is expressed by the following equation:resistance = [(resistivity x length) / cross-sectional area]So, resistance is directly-proportional to the resistivity and length of the material, and inversely-proportional to its cross-sectional area. So a high resistance can be obtained by increasing the length of the material or by decreasing its cross-sectional area, or by choosing a material with a high resistivity.It's also worth pointing out that resistivity is affected by temperature. For pure metals, the higher the temperature, the higher the resistivity, so the higher the resisistance. For example, a hot (i.e. an operating) tungsten lamp will have a much higher resistance than a cold tungsten lamp.
The resistance of any material is affected by its length, cross-sectional area, and resistivity. As resistivity varies with temperature, resistance is indirectly affected by temperature.Specifically, resistance is directly proportional to length and inversely proportional to cross-sectional area, and resistivity is the constant of proportionality.These factors apply to the conductors and all the components of your 'circuit' -including any insulation.
Resistivity is an intrinsic property of a material and is not affected by the dimensions of the material. Resistivity is determined by the material's composition and structure. The resistivity of a material remains constant as long as the material is uniform.
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.
Resistivity won't change. Resistivity is a material property that doesn't depend on the shape.
Yes, resistivity is dependent on the material of the conductor, not its dimensions. Resistivity is an intrinsic property of a material that influences its ability to resist the flow of electrical current.
No, a material with high resistivity is a poor conductor. Resistivity is a property that quantifies how much a material resists the flow of electric current. Materials with high resistivity impede the flow of current, making them poor conductors.
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.
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.
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.
The new resistivity of the wire will remain the same, as resistivity is a material property and is independent of the dimensions of the wire. The resistance of the wire will increase because of the increase in length.
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.
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.
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.
