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.).

So a wire with twice the diameter will have 1/4 the resistance (if you double the diameter of a wire it has 4 times the cross-sectional area).

∙ 14y agoThe reason why the resistance decreases as the wire gets thicker is because the resistance is proportional to the cross-sectional area of the wire therefore because the cross section of the wire is thicker it is letting the current flow past in a given amount of time.

Wiki User
∙ 14y agoAssuming wires are same material and same length then a thinner wire will have a higher resistance than a thick wire (proportional to cross sectional area).
Wiki User
∙ 13y agoThe thermal resistance of a wire is proportional to ln(r2/r1), meaning that a thicker wire has a greater thermal resistance.
Wiki User
∙ 9y agoIf two wires have the same length and are made of the same material,
then the thinner one has the greater resistance.

If two wires of the same material have the same thickness but different length the blank wire will have greater 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.
How does a wire's cross section affect resistance?
If two pieces of wire are made of the same material and have the same length but different resistance, then the one with the greater cross section area has the lower resistance.
Does electricity move better through thick or thin wire?
Electricity moves better through thick wire. This is because thick wires have a lower resistance and allows more current to pass through it. Now that might be true but I did an experiment with a thick wire,thin wire,light bulb,and D batteries and the thin wire made the light bulb light up brighter. So, really its probably a thin wire.
What falls faster 1kg iron or 1kg cotton?
If there was no wind resistance they would both hit the floor at the same time... however, and since such an atmosphere doesn't exist, (Wind resistance acting on cotton is greater because it has a greater surface area..) so iron will fall faster ... .
In freefall do heavier objects fall with a greater acceleration than lighter objects?
no, they fall the same acceleration ( one gravity ) neglecting air resistance; however they may reach different velocities with air resistance.
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.
If two wires of the same material have the same thickness but different length the blank wire will have greater 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.
Thin wires have a what resistance to electron flow than do thicker wires?
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.
Is it true that for the same resistance the greater the voltage the greater the current?
true
Is a wire thick with low electric resistance?
A wire that is thicker than another wire of the same material has less resistance
How does a wire's cross section affect resistance?
If two pieces of wire are made of the same material and have the same length but different resistance, then the one with the greater cross section area has the lower resistance.
A triangle with all sides the same lenght?
A triangle with all sides the same lenght is an equilateral triangle.
Do thin wires have a greater or lesser resistance to electron flow than do thicker wires?
Thinner wire has greater resistance than thicker wire, assuming the same amount of current.
Do all guys have the same lenght penis?
No.
The resistance of an extension cord varies directly with the length of the cord?
This means that as the length of the extension cord increases, the resistance also increases. Similarly, if the length decreases, the resistance will decrease as well. This relationship is described by the equation R = kL, where R is the resistance, L is the length, and k is a constant.
Why longer thinner wires produce more heating than short thick wires?
First of all, that's only true if the current through the thin wire is the same or greaterthan the current through the thick wire.The power dissipated from anything carrying current is(the current through it)2 x (its resistance)Making a wire thinner OR longer increases its resistance, so if the current remains thesame, then [ I2R ] must be greater.
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.
