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

What doesn't affect the resistance of a uniform circular copper wire?

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


What increases resistance in a 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.


What four factors determine the amount of resistance in a circuit?

Material that makes up the wire, length of wire, diameter of wire, and temperature of wire


What does resistance in wire depend on?

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.


Reducing voltage in a circuit does not affect resistance?

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.

Does the temperature of the wire affect the current?

Yes, the temperature of the wire can affect the resistance of the wire, which in turn can affect the current flowing through it. As the temperature increases, the resistance of the wire also increases, which can reduce the current flow.


What three factors affect the resistance in a circuit?

The three main factors that affect resistance in a circuit are the material the wire is made of, the length of the wire, and the cross-sectional area of the wire. Other factors, such as temperature and temperature coefficient of resistance, can also impact resistance.


What are factors that affect resistance of electricity?

Factors that affect resistance of electricity include the type of material the wire is made of (e.g. copper vs. aluminum), the length of the wire (longer wires have higher resistance), and the cross-sectional area of the wire (thicker wires have lower resistance). Temperature also affects resistance, with higher temperatures typically leading to higher resistance.


What are 4 things that influence resistance in a wire?

The four main factors that influence resistance in a wire are the material of the wire, the length of the wire, the cross-sectional area of the wire, and the temperature of the wire. These factors determine how easily electrons can flow through the wire and affect its overall resistance.


What can affect the resistance of a wire?

The resistance of a wire can be affected by its length, cross-sectional area, material, and temperature. Longer wires have higher resistance, while thicker wires have lower resistance. Different materials have different resistivities, impacting resistance. Temperature can also influence resistance, with most materials increasing in resistance as temperature rises.

How does the thickness of the wire affect resistance?

A thicker wire has less resistance than a thinner wire.


Do bend in the wire effect the electric resistance?

Yes, bending the wire can potentially affect its electrical resistance. The resistance of a wire is influenced by its dimensions, material, and temperature. Bending a wire can alter its cross-sectional area, length, or even cause deformations that impact the flow of electrons and increase resistance.


What is effect of temperature on resistance of a wire?

As temperature increases, the resistance of a wire also increases. This is because as the temperature rises, the atoms in the wire vibrate more vigorously, causing more collisions with electrons and impeding the flow of current. This relationship between temperature and resistance is known as the temperature coefficient of resistance.

What happens to the resistance of copper wire as the temperature of the wire increases?

The resistance of copper wire increases as the temperature of the wire increases. This is due to the increase in collisions between free electrons and atoms in the wire, which hinders the flow of electricity.
