The thermal resistance of a wire is proportional to ln(r2/r1), meaning that a thicker wire has a greater thermal resistance.
A thin wire will have greater resistance than a thick wire of the same length. This is because resistance is inversely proportional to the cross-sectional area of the wire. Thinner wires have smaller cross-sectional areas, leading to higher resistance.
The thinner the wire, the higher the resistance. The thicker the wire, the resistance decreases. Think of it this way. The thick wire has more room for electrons to jump around, but the thin wire has less room.
The wire with smaller diameter (thinner wire) will have greater resistance. This is because resistance is inversely proportional to the cross-sectional area of the wire. Thinner wires have smaller cross-sectional area, leading to greater resistance.
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.).
true
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 insulation resistance remains the same throughout the entire length of the conductor.
A wire that is thicker than another wire of the same material has less resistance
no, they are the same length
They are the same length.
A wire with a larger cross section has lower resistance because there is more space for the electrons to flow through, reducing collisions. A smaller cross section increases resistance as there is less space for the electrons to move, causing more collisions and therefore higher resistance.
It is two times greater
