Resistance is measured in ohms and the amount of resistance that allows one ampere of current to flow when one volt is applied is one ohm.

What are the Factors that determine resistance value of electrical material?
The factors that determine the resistance value of an electrical material are its length, cross-sectional area, temperature, and resistivity. A longer material will have higher resistance, while a larger cross-sectional area will result in lower resistance. The resistance of a material also changes with temperature, with most materials increasing in resistance as temperature rises. Finally, resistivity is an intrinsic property of the material that determines how strongly it resists the flow of electricity.
What three factors determine the amount of resistance of a material?
In solids, the resistance varies directly as the length of the object and inversely as the cross-sectional ares of the object and coefficient of resistance of the material which is an inherent property that each solid (metal or other) has.
What 4 things determine an objects resistance?
The four factors that determine an object's resistance are its length, cross-sectional area, resistivity of the material, and temperature. These factors influence how difficult it is for electrons to flow through the material, affecting the overall resistance.
What four factors determine the resistance of a material and give examples of each?
The four factors that determine the resistance of a material are resistivity (intrinsic property of the material), length (longer length increases resistance), cross-sectional area (smaller area increases resistance), and temperature (increases in temperature usually increase resistance). Examples could be copper with low resistivity, a longer wire having higher resistance, a thinner wire having higher resistance, and a material like a semiconductor having resistance affected by temperature changes.
How does the type of the material affect resistance?
The type of material affects resistance because different materials have different inherent properties that determine how easily electrons can flow through them. In general, materials with higher resistivity will have higher resistance, while materials with lower resistivity will have lower resistance. Additionally, factors such as temperature and impurities in the material can also influence its resistance.
Which factor does not affect the resistance of a material?
The factor that does not affect the resistance of a material is the color of the material. Resistance is primarily determined by factors such as the material's dimensions, temperature, and composition.
Resistance is affected by a material's?
Resistance is affected by a material's resistivity, length, and cross-sectional area. Resistivity is an intrinsic property of the material, while length and cross-sectional area determine how much material the current must pass through.
What is PFA material?
Corrosion Resistance
Four factors that determine resistance of an object?
Length, cross section, material, temperature.AnswerWithout wishing to sound pedantic, there are only threefactors that affect resistance. These are the length, cross-sectional area, and resistivity of a material. Temperature affects resistivity.
What is the relationship between resistance and temperature in a material?
The relationship between resistance and temperature in a material is that as the temperature of the material increases, the resistance also increases. This is because higher temperatures cause the atoms in the material to vibrate more, which disrupts the flow of electrons and increases resistance.
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.
Describe how the resistance of a material is determined?
The resistance of a material is determined by its resistivity, which is a fundamental property of the material. Resistivity is a measure of how strongly a material resists the flow of electric current. It depends on the material's composition and its physical dimensions. The resistance of a material can be calculated using the formula: resistance = resistivity x (length / cross-sectional area).
