Resistance of a wire is inversely proportional to the square of its radius.
A thin wire will have higher resistance than a thick wire. This is because resistance is inversely proportional to the cross-sectional area of the wire - a thicker wire has a larger cross-sectional area compared to a thin wire, so it offers less resistance to the flow of current.
Lower in thick wires due to their larger cross-sectional area, which allows for more space for electrons to flow and reduces the resistance. Thicker wires also have less electrical resistance because they experience less heat loss, making them more efficient for carrying electrical currents over greater distances.
The thin wire has more resistance to the flow of electric current than the thick wire. If you connect the wires to a battery the battery will supply electrical pressure (voltage) and the wires serve similar to pipes that conduct water under pressure. A small pipe exhibits more resistance to the flow of water and a thin wire exhibits more resistance to the flow of electrons. However, as you point out different wire materials exhibit different resistances for equal sizes (silver conducts better than copper, etc.).
Resistivity is a property of the material only, not of the dimensions of the wire. The resistance of a wire is the resistivity times the length divided by the cross-section area. So a long wire has more resistance, a thicker wire has less resistance, even if they are both made of copper with the same resistivity.
A thin wire has more resistance compared to a thick wire due to its smaller cross-sectional area, which hinders the flow of electrons. Thicker wires offer less resistance as they provide more pathways for electrons to flow easily.
Thin wires have higher resistance to electron flow compared to thicker wires due to increased resistance caused by the smaller cross-sectional area of thin wires. Thicker wires have lower resistance because they offer less resistance to electron flow with their larger cross-sectional area.
Due to the less space available for the electrons to travel across the thinner wire.
A thin wire will have higher resistance than a thick wire. This is because resistance is inversely proportional to the cross-sectional area of the wire - a thicker wire has a larger cross-sectional area compared to a thin wire, so it offers less resistance to the flow of current.
Thin wires have a greater resistance rhan thick wires. Imagine a straw. The thinner the straw. the less liquid can get through. Wires work the same way.

The thermal resistance of a wire is proportional to ln(r2/r1), meaning that a thicker wire has a greater thermal resistance.
Thin wires have high resistance because they offer more obstruction to the flow of electrical current compared to thicker wires. This increased obstruction results in higher resistance, as described by Ohm's law.
Because the thick wire is, of course, thicker, it has more area than the thinner wire. This means more electrons can flow through. It's like a highway, the wider it is, the more cars that can pass through.
The thinnest bike tires available on the market are typically around 23mm wide. These thin tires are lighter and offer less rolling resistance, making them faster. However, they are also more prone to punctures and wear out faster compared to thicker tires. Thicker tires, around 25-28mm wide, provide better durability and puncture resistance but may not be as fast. Ultimately, the choice between thin and thick tires depends on your priorities for speed versus durability.
