Because resistance is inversely proportional to the cross sectional area of the wire and directly proportional to its length. R = p*L/A, where R is resistance (in Ohms), p is resistivity (property of the material, in Ohms*m), L and A are length and area of the wire.
And if you think about it, it makes perfect sense. In thick wire electrons have a lot of 'room' to move, they do not obstruct the path. If you imagine it is like a road with many free lanes - cars move fast and freely i.e. low resistance (or more scientifically, like many wires in parallel). Where as length is proportional to the resistance, since every small segment of wire adds more resistance to the total (many wires in series).
What else can I help you with?
A wire that is what would have the greatest electrical resistance?
A long and thin wire made of a material with high resistivity and low conductivity would have the greatest electrical resistance. The resistance of a wire is directly proportional to its length and inversely proportional to its cross-sectional area, so a long, thin wire will have a greater resistance compared to a shorter, thicker wire.
Is electric resistance greater in a short fat wire of a long thin wire?
Electric resistance is greater in a long thin wire compared to a short fat wire, due to the higher resistance associated with longer wires and thinner cross-sectional areas. Resistance is determined by the material's properties and dimensions, with length and cross-sectional area being key factors affecting resistance.
Which has the lowest resistance thin wire or thick 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.
What kind of wire would have the greatest electrical resistance?
A thin and long wire made of a material with high resistivity, such as nichrome or tungsten, would have the greatest electrical resistance.
Does a thin wire has more RESISTIVITy or a thin wire of the same material?
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.

Which offers more resistance to the flow of charge a thick wire or a thin wire?
Thin wire.
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.

Is electric resistance greater in a short wire or a long thin wire?
Resistance is the restriction of electrical flow in a component/wire/etc. If you think of a short fat wire as a short freeway and a long thin wire as a quiet country road then the answer is easy to find especially if you imagine 1 thousand cars all trying to travel the distance at once
What happens to resistance of the wire if the wire is short?
If the wire is short, its resistance will likely decrease. A shorter wire has less length for electrons to travel through, resulting in lower resistance according to the formula R = ρL/A, where R is resistance, ρ is resistivity, L is length, and A is 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.
Will a short thick metal wire have better resistance compared to a long narrow metal wire?
"Better" depends on how much resistance you need for your circuit design.A short thick wire will have less resistance than a long thin wire of the same substance.Whether that's better or worse depends on how you plan to use the wire.
Which has the greatest resistance a thick wire or a thin wire of the same length?
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.
