If you are asking if a hot wire has a greater resistance than a cold wire then the answer I would say is yes. Cold wires have always had less resistance than hot wires
As temperature increases resistance increases
As temperature increases, wire resistance increases proportionally.
Is either; A. the length of the wire B. the diameter of the wire c. the location of the wire D. the temperature of the wire
Current (measured by an ammeter) and Voltage (measured by a voltmeter) R= V/I Resistance equals voltage divided by current ================================ That's wonderful, but the measurement doesn't "affect" the resistance of the wire. The factors that do "affect" the resistance ... i.e. determine what the resistance will be ... are -- substance of which the wire is composed -- dimensions of the wire: thickness and length.
Resistance is directly proportional to the resistivity and length of the conductor, and inversely-proportional to its cross-sectional area. As resistivity is affected by temperature, we can say that temperature indirectly affects resistance.
Material that makes up the wire, length of wire, diameter of wire, and temperature of wire
Reducing voltage in a circuit does not directly affect resistance. It affects current. Resistance is an independent variable.Ohm's law: voltage equals current times resistance.However, reducing voltage and/or current does reduce power, which reduces temperature, which can change resistance because resistance is usually affected to some degree by temperature.
Temperature, thickness, length and type of wire.

A thicker wire has less resistance than a thinner wire.
A thicker wire has less resistance than a thinner wire.
no there will be no any affect on resistance of wire, when it bends
The thickness

In general, the longer the wire the greater the resistance. The only time that this is not so is when the wire is a superconductor, in which case the resistance is always zero.
Reduce the resistance:-- Use a shorter piece of wire.-- Use thicker wire.-- Cool the wire.Increase the resistance:-- Use a longer piece of wire.-- Use thinner wire.-- File a nick in the piece of wire you have.-- Stretch the wire.-- Heat the wire.
Wire is not equal to resistance. If you have two pieces of wire with the same thickness, composition, and temperature, the longer piece has higher electrical resistance.
You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).You can increase the resistance in the wire, by doing any of the following:Increase the length of the wire.Reduce the wire's cross-section.Change to a material that has a greater resistivity (specific resistance).
yes.it affect.because thick wire cannot hold high resistance of current
