Does a wire with a diameter of 0.01 mm have lower resistance than a wire with 0.1 mm?
No, a smaller diameter wire has a higher resistance. The 0.01 mm wire will have 1/100 the cross-sectional area of the 0.1 mm diameter wire, therefore the resistance will be 100 times as high.
A lenght of cirular wire as a resistance of 1 ohms if its the diameter was double its resistance woul be.?
Its resistance would be half , 0.5 ohms is the answer.
How does the resistance of a wire vary with its diameter?
At a greater diameter, the cross-section will also be greater, and therefore the resistance will be less. This assumes that other things are equal, of course.
Which would have the greater effect on vascular resistance?
decreasing the diameter of a blood vessel by ½by hussain :)
Can copper and alluminium wire of same length and diameter have same resistance?
For a single temperature, yes. The copper wire will have a much smaller cross-section than the iron wire. For multiple temperatures, no. Copper and iron have different temperature coefficients for resistivity.
Does a wire with a diameter of 0.01 mm have lower resistance than a wire with 0.1 mm?

Do thicker or thinner wires have more Resistance?
Over the same distance the larger diameter wire will have less resistance that the smaller diameter wire.
A thicker resistance wire produces more heat?
I'm not sure what you mean by "thicker resistance" wire? The thicker or more diameter of a wire the less resistance it has. A larger diameter wire would produce less heat. More resistance would produce more heat.
A piece of wire 100 m long has a diameter of 1 mm with a resistance of 2 ohms calculate the resistance of the same wire 2 km long with the same current?
If the wire length is 100m and the Diameter is 1mm calculate the Resistance of wire?
Does the diameter of the wire affect resistance?
Yes. Other things being equal, a thicker wire has less resistance.
How does the material of wire affect the resistance?
Basic: The larger the diameter the less resistance.Deep:R = p (L / A)The resistance is proportional to the length of the wire divided by its cross-sectional area. p is the resistivity of the material in question and varies greatly. Since area (assuming a circular wire) is A = pi * r2 the larger the diameter of the wire the lower its resistance will be.AnswerResistance is inversely proportional to the square of the diameter. So, if you double the diameter, you will quarter the resistance. If you halve the diameter, you will quadruple the resistance.
What factors effect the resistance of a wire?
Its elemental makeup. Its' diameter and its' 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.

Which wire would have the least resitance a large diameter or small diameter wire and why?
large diameter wire simply because it will move easier Technically they would have the same resistance, but the larger diameter wire would allow more current to flow as it would have more room to move.
How can we Find wire's gauge by use of wire's diameter?
