Area of cross section: Resistance R is inversely proportional to the area of cross section ( A) of the conductor. This means R will decrease with increase in the area of conductor and vice versa. More area of conductor facilitates the flow of electric current through more area and thus decreases the resistance. This is the cause that thick copper wire creates less resistance to the electric current.

What happens to resistance of the wire if the wire is short?
Short wire has less resistance Long wire has more resistance Thick wire has less resistance Thin wire has more resistance
Which offers more resistance to the flow of charge a thick wire or a thin wire?
Thin wire.
Does thin wires have high or low resistance?
Other things being equal, a thin wire will have a higher resistance than a thick wire.
Is the wire gets thicker or thin when the resistance is less?
Resistance of a wire is inversely proportional to the square of its radius.
Why the thin wire has grater resistance to electricity?
it has to do with ohms and the gauge of the wire. if you have a low ohms then you can't use a small thin wire. because the more ohms the more resistance. if you have a low omhs on a thin wire it can cause the wire to heat up. posibly catch fire.
Which has the greater resistance thick wire or a thin of the same length?
The thermal resistance of a wire is proportional to ln(r2/r1), meaning that a thicker wire has a greater thermal 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.
What is the measure of the voltage decrease along a wire?
Decrease or reduction of voltage along the wire is called voltage drop. It is measure through wire and load resistance difference.
Which has more resistance a thick or a thin wire?
For a given material, a wire of smaller cross-section will have higher resistance per unit length.
What is one thing that you could do to the wire used in a circuit to decrease the amount of resistance bulb by the wire?
Use thicker wire. Doubling the diameter gives one quarter the resistance.
Does heating a metal wire increase or decrease its electrical resistance?
it so increases it
Which has greater resistance a thick wire or a thin wire of the same lenght?
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.).
