What type of wire increases when it is made thinner?
Since resistance is inversely-proportional to cross sectional area, the lower the cross-sectional area, the higher the resistance. So ALL types of wire exhibit this behaviour!
Does the resistance of a wire depend on the cross section area of the wire?
No, the resistance of a wire primarily depends on its length, resistivity, and temperature. The cross-sectional area of the wire influences the wire's resistance indirectly by affecting the wire's overall resistance. A larger cross-sectional area generally results in lower resistance due to increased conducting area for current flow.
What is the cross sectional area of a wire?
If you slice a wire cleanly and then look at the cut end, you see a little circle at the end. The area of that circle is the "cross-sectional area" of the wire. The larger that area is, the lower the DC resistance of the wire is.
Would a long and thick wire have the greatest resistance?
No, resistance is primarily determined by the material the wire is made of, its length, and its cross-sectional area. A longer and thicker wire would actually have lower resistance due to more space for electrons to flow through.

What effects the restance of an electrical conductor?
The resistance of an electrical conductor is primarily affected by its length, cross-sectional area, and the material it is made of. Longer conductors have higher resistance, while conductors with larger cross-sectional areas have lower resistance. Different materials have different resistivities, which also affect resistance.
What are three things resistance of a wire depends on?
The resistance of a wire depends on its length - longer wires have higher resistance. It also depends on the material of the wire - materials with higher resistivity have higher resistance. Lastly, the cross-sectional area of the wire affects resistance - larger cross-sectional areas have lower resistance.
How does the resistance of a wire depend on its dimensions?
The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area. This means that for a given material, a longer wire will have higher resistance and a thicker wire will have lower resistance. The relationship is described by the formula: Resistance = resistivity x (length / cross-sectional area).
What has a lower resistance a long thin iron wire at high temp or a short thick copper wire at low temp?
A short thick copper wire at low temperature would have lower resistance compared to a long thin iron wire at high temperature. This is because resistance is inversely proportional to cross-sectional area and directly proportional to temperature and length of the wire. The short thick copper wire has a larger cross-sectional area, which results in lower resistance.
What factors affect the speed of current flow?
The factors that affect the speed of current flow include the material through which the current is flowing (conductivity), the cross-sectional area of the conductor, the voltage applied, and the resistance in the circuit. A higher conductivity material, larger cross-sectional area, higher voltage, and lower resistance will result in a faster current flow.
How does the resistance change as the wire become thicker?
As the wire becomes thicker, the resistance decreases. This is because a thicker wire has more cross-sectional area, allowing more space for electrons to move, resulting in lower resistance to the flow of electrons. Thinner wires have higher resistance due to a smaller cross-sectional area, limiting the flow of electrons.
How can you reduce the resistance in a wire?
You can reduce the resistance in a wire by increasing the cross-sectional area of the wire, using a material with lower resistivity, or shortening the length of the wire. These methods can help to lower the resistance and improve the flow of electric current.
