What causes a wire to become warm when current flows through it?
When an electric current flows through a wire, the wire becomes warm due to the resistance of the wire. The resistance in the wire causes some of the electrical energy to be converted into heat energy, which raises the temperature of the wire.
What change to a wire would cause its resistance to decrease?
Decreasing the length or increasing the thickness of the wire would cause its resistance to decrease.
What causes a wire to get hot?
A wire gets hot when an electric current flows through it, causing resistance in the wire which generates heat.
What causes heating in wire?
Heating in wire is caused by the flow of current through the wire. The resistance in the wire causes energy to be converted into heat as the electrons move. This heating effect is known as Joule heating.
What is relationship between resistance and heat as electricity flows through a wire?
As electricity flows through a wire, resistance causes some of the electrical energy to be converted into heat. The heat produced is proportional to the amount of current flowing through the wire and the resistance of the wire. Higher resistance in the wire will result in more heat being generated.

What happens to the resistance of a copper wire when it is heated?
The resistance of a copper wire increases when it is heated. This is because heating the wire causes the metal ions to vibrate more, increasing collisions with the electrons and hindering the flow of current, therefore increasing resistance.

What factor can change the amount of resistance in a wire?
Rubba Bubba Rubber coating, around the wire
How do you change the current in a wire?
To change the current in a wire, you can adjust the voltage applied to the wire or change the resistance in the circuit. Increasing the voltage will increase the current as per Ohm's Law (I = V/R), while decreasing the resistance will also result in an increase in current.
Describe how the electric resistance of a wire changes as the wire becomes longer. How does the resistance change as the wire becomes thicker?
As the wire becomes longer, its resistance increases because there is more material for the electrons to travel through. On the other hand, as the wire becomes thicker, its resistance decreases because there is more space for the electrons to flow, reducing the collisions with the wire material and therefore lowering the 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).
Why is the lamp wire hot?
The lamp wire is hot because electrical current flowing through it encounters resistance, which causes the wire to heat up.
