What determines the electrical resistance of a material?
The electrical resistance of a material is determined by factors such as the material's composition, temperature, length, and cross-sectional area. Conductors have low resistance due to their high electron mobility, while insulators have high resistance due to limited electron flow. Resistance increases with longer length and smaller cross-sectional area.
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 are some words to describe lava girl?
Fiery, powerful, determined, mysterious.
Which common factor affect both resistance as well as resistivity and how?
Temperature is a common factor that affects both resistance and resistivity. An increase in temperature generally leads to an increase in resistance and resistivity of a material. This is because higher temperature causes more atomic vibrations and collisions within the material, hindering the flow of electrons and increasing resistance.
Which of the following is the term used to describe a bodys resistance to a change in motion a inertia b acceleration c gravity d mass?
Type your answer here... A. inertia
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.
What does not affect a material resistance?
Material resistance is not affected by color, texture, or surface finish. It is primarily determined by the material's intrinsic properties such as conductivity, thickness, and temperature.
Describe the cause of resistance of a wire can be determined?
The resistance of a wire is determined by its material, length, cross-sectional area, and temperature. Higher resistance is caused by longer wires, smaller cross-sectional areas, higher resistivity materials, and higher temperatures. These factors affect the flow of electrons and ultimately the opposition to the current flow in the wire.
What does not affect electrical resistance?
Electrical resistance is primarily determined by the material's properties (resistivity, temperature, dimensions) and not affected by factors like voltage or current. However, the type of material, temperature, and length can impact resistance.
If voltage is high will the resistance be high?
The electric resistance is related to the diameter and extension of the wire submitted to a determined voltage which will determine the electric current flowing into the wire.AnswerVoltage has no effect on resistance. Resistance is determined by the length, cross-sectional area, and resistivity of a material (resistivity is affected by temperature, so temperature indirectly affect resistance).
What determines the electrical resistance of a material?
The electrical resistance of a material is determined by factors such as the material's composition, temperature, length, and cross-sectional area. Conductors have low resistance due to their high electron mobility, while insulators have high resistance due to limited electron flow. Resistance increases with longer length and smaller cross-sectional area.
What is the measure of how difficult it is for charges to flow through a material?
The measure of how difficult it is for charges to flow through a material is called electrical resistance. It is quantified in ohms and is determined by factors such as material composition, dimensions, and temperature.
What freature of an object does not affect air resistance?
The internal composition or material of an object does not affect air resistance. Air resistance is mainly determined by an object's size, shape, and speed when moving through air.
What happens to the resistance when the frequency is doubled?
When the frequency is doubled, the resistance of a circuit remains unchanged. Resistance in a circuit is independent of frequency and is determined by the material and physical dimensions of the resistor.
What is bulk resistivity?
Bulk resistance is the ohmic resistance of the semiconductor material. The natural resistance of a "P" type or "N" type semiconductor material.
When electrons are not allowed to pass through a material this opposition to current is known as?
When electrons are not allowed to pass through a material, the opposition to current flow is known as resistance. Resistance is measured in ohms and is determined by the material's properties such as its composition, length, and cross-sectional area.
Is resistance is directly proportional to charge?
No, resistance is not directly proportional to charge. Resistance is determined by the material, length, and cross-sectional area of a conductor, while charge is a property of matter. The resistance will affect the flow of charge in a circuit, but it is not directly proportional to the charge itself.
