Resistance will only be reduced by changing the thickness / physical dimensions (15 small wires wound together vs 1 big one, etc.) of the wire, or the wire's temperature. It's apparent impedance can be changed by placing it in an electric field as well.
What else can I help you with?
The properties of a wire that would create the least resistance to electron flow?
Generally a larger diameter copper wire would create the least resistance to electron flow. Copper is the most conductive and is widely used.
Stretch a copper wire so that its thinner and the resistance between its end?
increases
What is difference between ofc and copper wire?
The main difference is in the price. Oxygen-free copper is sold to people with plenty of money for loudspeaker wire, but provided the wire has less resistance than one tenth of the speaker resistance (usually 4 or 8 ohms), the resistance of the wire is immaterial, and ordinary copper wire is perfectly all right. Highly refined copper has about 1% better conductivity than the usual variety. That difference in conductivity is insignificant for audio use and is also produced by a 3 degree C temperature rise in copper.
What doesn't affect the resistance of a uniform circular copper wire?
Is either; A. the length of the wire B. the diameter of the wire c. the location of the wire D. the temperature of the wire
How do you reduce the copper losses in transmission lines?
Using larger amounts of copper will decrease copper loss (use bigger wire than necessary).
What would not reduce resistance in the copper wire?
Increasing the length of the wire will not reduce resistance in a copper wire. In fact, resistance is directly proportional to the length of the wire according to the formula R = ρ * (L/A), where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.
What would reduce resistance in a copper wire?
Reducing the temperature of the wire will decrease its resistance. Also, using a wire with a larger cross-sectional area will lower resistance since there is more room for electrons to flow. Finally, using a more conductive material than copper, such as silver, can reduce resistance.
Would not reduce resistance in a copper wire?
Resistance will only be reduced by changing the thickness of the wire or the wire's temperature. It's apparent impedance can be changed by placing it in an electric field as well.
What copper wire would have the highest resistance?
A thicker copper wire will have higher resistance as it will offer more opposition to the flow of electrons compared to a thinner wire. Additionally, a longer copper wire will have higher resistance compared to a shorter wire due to increased distance for the electrons to travel. Finally, a copper wire with impurities or defects will have higher resistance than a pure copper wire.
Which material has a greater resistance aluminum or copper wire?
Copper wire has greater resistance than aluminum wire. This is because copper is a better conductor of electricity than aluminum. This means that copper wire will have less resistance and will be able to carry more current with less energy loss.
How can resistance be reduced in wire?
Resistance in a wire can be reduced by using a thicker wire or a material with lower resistivity, like copper. Keeping the wire short and straight also helps reduce resistance. Additionally, ensuring good connections and minimizing temperature fluctuations can further decrease resistance.
What is the resistance value of 1 meter copper wire?
The resistance value of a 1 meter copper wire depends on its gauge (thickness) and temperature. For example, a 1 meter wire of 24-gauge copper has a resistance of about 25.67 ohms at room temperature. It is important to consider these factors when calculating the resistance of copper wire.
How is copper losses reduced in transformers?
how to reduce copper losses in a transformer Copper losses are due to the resistance of the copper (or aluminum) windings. To reduce copper losses the transformer would have to be rewound with heavier gage wire.
Can copper and alluminium wire of same length and diameter have same resistance?
No, copper and aluminum wire of the same length and diameter will not have the same resistance. Copper has a lower resistivity than aluminum, so a copper wire will have lower resistance compared to an aluminum wire of the same length and diameter.
What has the lowest resistance copper wire or iron wire?

What are the dependent variables in a copper wire resistance experiment?
The dependent variables in a copper wire resistance experiment would typically be the resistance of the copper wire being measured. This would vary based on factors like the length and thickness of the wire, as well as the temperature.
Which wire would have the lowest resistance a long thin iron wire at a high temperature or a short thick copper wire at a low temperature?
The short thick copper wire at a low temperature would have the lowest resistance. Copper has lower electrical resistance than iron, and a shorter, thicker wire has lower resistance compared to a long thin wire, regardless of the temperature.
