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 else can I help you with?
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.
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.
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 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 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.

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.
The magnitude of the resistance of a wire depends on?
Temperature, Length of wire, Area of the cross-section of wire and nature of the material.
What is the effect of temperature on specific resistance of wire?
As temperature increases, the specific resistance of a wire typically also increases. This is because at higher temperatures, the atoms in the wire vibrate more vigorously, which disrupts the flow of electrons and increases the overall resistance of the wire. Conversely, at lower temperatures, the atoms have less thermal energy and are less likely to impede electron flow, resulting in lower 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.
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.
