What is effect of temperature on conductor?
It depends on the material. In metals, the resistance increases with temperature.
What do you mean by heating effect of current?
The heating effect of current refers to the phenomenon where the flow of electric current through a conductor leads to the production of heat. This occurs due to the resistance offered by the conductor to the flow of electrons. The amount of heat produced is directly proportional to the square of the current and the resistance of the conductor.
Does a good conductor has a high resistance?
No, a good conductor has a low resistance.
What are the factors that effect air resistance?
size , shape , and speed of the object
What has the least amount of resistance a semi conductor insulator resistor or a conductor?
Traditionally, a conductor has the least resistance of the three, followed by the semiconductor and finally the resistor.
What factors effect the distance of an electric circuit?
the factors that effect are ,temp,volts,amperes,lentzs law governing electic,which is very common to volkmans law,,,,which is called back flux resistance +resistance of the conductor
What are the factors that affect the resistance of a conductor?
the amount of fluctuating current and heat will effect resistancephysical properties as well as impurities
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!
What is effect of resistance in heat production in a current carrying conductor?
resistance will be high
What are the factors that affect resistance?
The factors are: length, cross-sectional area and nature of substance.
What would be the effect of resistance of a conductor of doubling its diameter?
doubles
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.
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 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.
Factors affecting resistance of a metal conductor?
The material, the length, the cross section.
What is effect of temperature on conductor?
It depends on the material. In metals, the resistance increases with temperature.
