What can affect the resistance of a wire?
The resistance of a wire can be affected by its length, cross-sectional area, material, and temperature. Longer wires have higher resistance, while thicker wires have lower resistance. Different materials have different resistivities, impacting resistance. Temperature can also influence resistance, with most materials increasing in resistance as temperature rises.
What affects the electrical resistance of a body?
The electrical resistance of a body is affected by the material it is made of, its length, cross-sectional area, and temperature. Materials with high resistivity, longer lengths, smaller cross-sectional areas, and higher temperatures will have higher electrical resistance.
What effects the restance of an electrical conductor?
The resistance of an electrical conductor is primarily affected by its length, cross-sectional area, and the material it is made of. Longer conductors have higher resistance, while conductors with larger cross-sectional areas have lower resistance. Different materials have different resistivities, which also affect resistance.
Do all conductors have resistance?
Yes, all conductors have resistance to some degree. Resistance is a property of materials that impedes the flow of electric current. However, some materials have lower resistance (e.g., copper) while others have higher resistance (e.g., rubber).
Why the nature of materials affect the resistance?
The nature of materials affects resistance because different materials have varying numbers of free electrons, which are responsible for conducting electricity. Materials with more free electrons, like metals, have lower resistance since electrons can flow more easily through them. Conversely, insulating materials have high resistance because they have very few free electrons available for conducting electricity.

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 is a resistance of a material?
Resistance is the opposition to the flow of electric current. It is affected by the length, cross-sectional area, and resistivity of a material. As resistivity is affected by temperature, temperature indirectly affects resistance.
When bacteria are not affected by antibiotics they have?
They have resistance to the antibiotic.
What are the materials have low resistance?
Conductors.
How is a current affected across a wire if its resistance increases?
As the resistance increases the temperature will also increases....
How many ohms does a 9v produce?
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.

Conversely, insulating materials have high resistance because they have very few free electrons available for conducting electricity.
What material does resistance depend on?
Resistance depends on the material's conductivity, temperature, and dimensions. Materials with high conductivity exhibit low resistance, while materials with lower conductivity exhibit higher resistance. Temperature can also affect resistance, with most materials experiencing an increase in resistance as temperature rises. Additionally, resistance is directly proportional to the length of the material and inversely proportional to its cross-sectional area.
