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.
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 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.
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.
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.

Three ways which resistance of a wire can be increased?
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).
What will be the effect on specific resistance if length of wire is halved?
it will not effect it because it only depends upon property of medium
How does temperature affect resistance of a wire?
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
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 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 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.
Which wire would have the lowest resistance a long thin iron wire at a high temperature or a short thick copper wire at a low temperature?
The short thick copper wire at a low temperature would have the lowest resistance. Copper has lower electrical resistance than iron, and a shorter, thicker wire has lower resistance compared to a long thin wire, regardless of the temperature.
What would reduce resistance in a copper wire?
Reducing the temperature of the wire will decrease its resistance. Also, using a wire with a larger cross-sectional area will lower resistance since there is more room for electrons to flow. Finally, using a more conductive material than copper, such as silver, can reduce resistance.

What is the resistance value of 1 meter copper wire?
The resistance value of a 1 meter copper wire depends on its gauge (thickness) and temperature. For example, a 1 meter wire of 24-gauge copper has a resistance of about 25.67 ohms at room temperature. It is important to consider these factors when calculating the resistance of copper wire.
