What is effect of resistance in heat production in a current carrying conductor?
resistance will be high
What three things effect the value of the applyed voltage in a conductor?
Lenght, diameter and material of the conductor.
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.
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 temperature on conductor?
It depends on the material. In metals, the resistance increases with temperature.
What factors effect the resistance of a wire?
Its elemental makeup. Its' diameter and its' length.
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.
What is the effect on the projectile motion when the diameter of the object is changed?
-- In the absence of air resistance, the object's diameter has no effect at all on the projectile motion. -- In the presence of air resistance, one has to know everything about the object AND the air in order to have a prayer of calculating the effect.
Would doubling the length of a blood vessel have the greater effect on vascular resistance?
In which of the following would the blood flow be highest? A) a vessel 0.5 cm in diameter and 4 meters long B) a vessel 1.0 cm in diameter and 10 meters long C) a vessel 0.5 cm in diameter and 2 meters long D) a vessel 1.0 cm in diameter and 2 meters long
What is the Change in resistance of wire when its length is double?
Assuming the wire follows Ohm's Law, the resistance of a wire is directly proportional to its length therefore doubling the length will double the resistance of the wire. However when the length of the wire is doubled, its cross-sectional area is halved. ( I'm assuming the volume of the wire remains constant and of course that the wire is a cylinder.) As resistance is inversely proportional to the cross-sectional area, halving the area leads to doubling the resistance. The combined effect of doubling the length and halving the cross-sectional area is that the original resistance of the wire has been quadrupled.
If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
What is skin effect in power system?
DEFINITION: Nonuniform density of current due to its characteristic to flow more at the surface of the conductor than that of the other section of the conductor called Skin Effect in power system.EFFECT: Due to the skin effect, whole section of the conductor can not be utilized properly. Moreover, skin effect causes increment in effective resistance of the conductor and in power loss.
