There are three, not four, factors that determine the resistance of a conductor. These are the length of a conductor, its cross-sectional area, and its resistivity.
As resistivity is affected by temperature, you could say that temperature indirectly affects resistance but, strictly, temperature is affecting the resistivity not the resistance -which is why it is not considered a 'fourth' factor.
So, resistance = resistivity x (length/area)
What else can I help you with?
When the diameter of a wire is doubled its resistance becomes .?
When the diameter of a wire is doubled, its cross-sectional area increases by a factor of four. Resistance is inversely proportional to cross-sectional area, so the resistance would decrease by a factor of four.
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.
What are four factors that determine the amount of runoff?
The first factor is the amount of rain an area receives, the second factor is vegetation, the third factor is the type of soil, the fourth factor is the shape of land, and the final factor is how people use the land.
A lenght of cirular wire as a resistance of 1 ohms if its the diameter was double its resistance woul be.?
If the diameter of the circular wire is doubled, the resistance will decrease by a factor of four, resulting in a resistance of 0.25 ohms. Resistance is inversely proportional to the cross-sectional area of the wire, which is affected by the diameter.
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.
Why doubiling the radius of a copper wire leads to decreasing its resistance to one quarter?
If you double the radius of a wire then its cross-sectional area goes up by a factor of four. Put in the simplest way, this means that there's four times as much space for electrons to flow along the wire, hence one quarter the resistance.
What is the reciprocal of the power factor?
impedance/resistance
What are the factor affecting resistance?
The availability of food is an example of a factor that affects environmental resistance. Other factors include climate and predators.
Why in coil power factor is low?
A coil of wire acts as an inductor; it will have a very small resistance, and a relatively large inductance. Power factor is effectively the resistance divided by the impedance (made up of resistance and inductance), so the larger the inductance relative to the resistance, the lower the power factor will be.
What are 4 things that influence resistance in a wire?
The four main factors that influence resistance in a wire are the material of the wire, the length of the wire, the cross-sectional area of the wire, and the temperature of the wire. These factors determine how easily electrons can flow through the wire and affect its overall resistance.
How do you get the power factor?
Resistance divided by impedence
