What are the factors that affect the resistance of a conductor?
The factors that affect the resistance of a conductor are the material it is made of, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor. Materials with high resistivity, longer lengths, smaller cross-sectional areas, and higher temperatures will have higher resistance.
What regulates amperage in a conductor?
Amperage in a conductor is primarily regulated by the voltage across the conductor and the resistance of the conductor itself, as described by Ohm's Law (I = V/R). When voltage increases, amperage increases, provided the resistance remains constant. Conversely, higher resistance results in lower amperage for a given voltage. Additionally, factors such as temperature and the material properties of the conductor can also influence resistance and thus affect amperage.
What is the most important factor in determining airway resistance?
The diameter of the airway is the most important factor in determining airway resistance. A smaller diameter increases resistance, making it harder for air to flow. Factors such as mucus, inflammation, and constriction can also affect airway resistance.
What affects electrical resistance?
Primary Factors:For a simple system like an electrical wire, there are three major things which will affect the electric resistance.1. Resistance of wire conductor depends upon the material of which it is made.2. Resistance of wire conductor is directly proportional to its length.3. Resistance of a wire conductor is inversely proportional to its area of cross-section. (At least for low frequency voltage.)Additional:In general every material has a characteristic electrical conductivity (and resistivity) which determines how well it will conduct electricity. Metals have very high conductivities and insulators very low. The geometry of an object affects the resistance with the above-mentioned wire geometry being the most important example.In general the type of material and the geometry are the primary factors in determining the resistance of an object, but there are other effects worth mentioning.Temperature can change electrical properties of a material and there are some dramatic examples such as superconductors. Semiconductors can also have important temperature dependent properties. For most generic materials there is a rise in resistance with an increase in temperature but the effect is not usually large.More exotic phenomena also exist, such as the change in resistance due to a magnetic field or nonlinear conductors which do not have a fixed resistance but rather have a resistance that depends on voltage. Conductivity through a gas is a dramatic example of the latter.
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 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.
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.
What 4 things affect resistance?
The four things that affect resistance are the material of the conductor, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor.
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 happens to the resistance of the conductor if the conductors become longer but the diameter stays the same?
If the length of the conductor increases while the diameter remains constant, the resistance of the conductor will increase. Resistance is directly proportional to the length of the conductor, so a longer conductor will have higher resistance. The diameter, however, does not directly affect resistance as long as it remains constant.
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 are the factors that affect the resistance of a conductor?
The factors that affect the resistance of a conductor are the material it is made of, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor. Materials with high resistivity, longer lengths, smaller cross-sectional areas, and higher temperatures will have higher 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 factor that govern the value of resistance in a resistor?
It can be because of the material used.As we know R=PL/A where R=resistance P=resistivity of the material used L=length of the conductor A=area of cross section of the conductor
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.
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is decreased?
The resistance of a conductor is directly proportional to the resistivity of the conductor. since the resistivity of a conductor is decreases with decrease in temperature hence the resistance.
What factors contribute to the electrical resistance of a conductor?
1) What materials the conductor is made of;2) the average cross-sectional area along the length of the conductor;3) the temperature of a conductor also affects its resistance;4) the length of the conductor is also very important.Generally, the longer the conductor, the higher its resistance.Your students' course materials can probably give you a better answer than mine, or at least you'll know it is the right one.The length, the cross sectional area, temperature of conductor along with the intrinsic property called the specific resistance of the substance.
