Five factors that affect resistance?
Electrical Resistance depends on three factors: Resistivity; Area; Length.Resistivity is the property of the matter. More Resistivity means more resistance.More Area means less resistance.More length means more resistance.R= Resistivity. Length/Area
What factors affect rock failure and resistance?
Hydrology Erosion Tectonic activity
What is the resistance of a conductor directly proportional to?
The resistance of a conductor is directly proportional to several different factors.Here is a list of some of them:the cross-sectional area or thickness of the conductor;the overall length of the conductor;the resistivity of the material from which the conductor has been made - note that this is often dependant on its actual temperature;the actual temperature the conductor reaches after a steady electric current has been passing through it for sufficient time for everything to stabilize.
What is the meaning of short circuit conductor?
A short circuit conductor is just a conductor in an unexpected location, often with much lower resistance that is expected for the normal load.
How would you descibe a good conductor?
Something that conducts electricity with little resistance. one really good conductor is metal.
What are the factors that affect resistance?
The factors are: length, cross-sectional area and nature of substance.
Does the length of a conductor not affect its resistance?
The length of a conductor Does affect it's resistance.The longer it is, the more the resistance.
Resistance of a copper conductor will decrease with an increase of applied voltage?
Resistance is affected by the length, cross-sectional area, and resistivity of the conductor. The resistivity, in turn, is affected by temperature. So only by changing one of these four factors will the resistance of a conductor change. Changing voltage will have no affect upon the conductor's resistance.
What factors effect the resistance of a conductor?
Factors affecting the resistance of a conductor include the material from which it is made, its length, its cross-sectional area, and its temperature.
What causes resistance to increase or decrease?
Voltage, if voltage is increased resistance in the circuit increasesAnswerResistance is determined by the length, cross-sectional area, and resistivity of a conductor. Resistivity is, in turn, affected by temperature -so temperature indirectly affects resistance.These are the only factors that affect resistance. Voltage and current have no direct effect whatsoever on resistance. Current can affect resistance indirectly if it causes the conductor's temperature to increase.For AC circuits, 'skin effect', due to frequency, causes the current to flow towards the surface of a conductor which acts to reduce the effective cross-sectional area of that conductor. So, frequency can also indirectly affect resistance.
Name four factors affecting the resistance of a conductor?
area of the conductor, length of the conductor and temperature around the conductor..........
What are the factors affecting the resistance of conductors?
Conductor resistance = Conductor resistivity * Length of conductor / Cross sectional area of conductor. So. It is directly proportional to material & conductor length. And inversely proportional to the cross sectional area of conductor.
What factor affects the resistance of a conductor?
This are the factor which affect resistance of a conductor (1). Area of conductor (2). Length of conductor (3) Temperature (4). Type or substance of material used in conducting the electricity.
How Magnetism effect resistance?
Magnetism does not affect the resistance of a conductor. The factors affecting resistance are the conductor's length, cross-sectional area, and resistivity. As resistivity is affected by temperature, temperature indirectly affects resistance. However, the changing magnetic field surrounding a conductor carrying an AC current causes the current to flow closer to the surface rather than being distributed throughout the cross-section of the conductor. The greater the frequency, the greater this effect. This has the equivalent effect of reducing the cross-sectional area of the conductor, causing its resistance to rise. This is misleadingly called the 'AC resistance' of the conductor!
Factors affecting resistance of a metal conductor?
The material, the length, the cross section.
Five factors that affect resistance?

What increase and decrease resistance?
Increase in resistance means that when the resistance of the substance increase by application of some external sources like temperature etc. or when the flow of current through the substance gradually decreases then the resistances increases. Vice versa in case for decrease in resistance.Alternative AnswerResistance is determined by the length, cross-sectional area, and resistivity of a conductor.
