Why does conductor heat up when current is passed through after a long time?

Heating up means increase in average speed of atoms oscillation. When current passes through the conductor electrons collide (impact) with atoms and transfer a part of their energy to them increasing their average speed.
Error: "average" instead of "average"

Does every conductor heat up when electric current is passed through it?
yes every conductor heat up fast
Why the temp of metallic wire rises when a current passes through it?
When current is passed through the wire, the negatively charged electrons (Current) face resistance as the molecules of the conductor block their way. These moving electrons collide with the molecules of the conductor and heat is produced which heats up the metallic wire.
What do you mean by heating effect of current?
The heating effect of current refers to the phenomenon where the flow of electric current through a conductor leads to the production of heat. This occurs due to the resistance offered by the conductor to the flow of electrons. The amount of heat produced is directly proportional to the square of the current and the resistance of the conductor.
Is a light bulb an insulator or conductor?
It is a conductor, but the filament is a resistor : as current flows through the filament, some of the energy is released as heat and light.
When current passes through a conductor what makes the conductor heat up?
The electrical resistance of the material. All materials have some electrical resistance except for superconductors.

What happens when electric current is passed through Cu wire?
as a cu wire is a conductor, electrical current does go through it, but some of the electrical energy gets converted into heat energy, and that is why the wire aslo heats up a bit.
Is gold metal a good conductor of heat?
yes, because it is a fabulous conductor of heat

What source of heat does a halogen light use?
an electric current passed through it
What is the definition of conductors and insulators?
A conductor is a material that can transfer energy efficiently and and insulator is the opposite.Conductor means something that blocks it and insulator means something that can go through itA conductor easily transfers energy in the form of electricity and/or heat, while an insulator does not easily transfer these types of energy.In electricity, a conductor is a material that can let current pass through and an insulator does not let current pass through,or rather copper is a conductor and plastic is an insulator.A insulator is something that will not allowheat/electricity to pass through it and a conductor is something that allows heat/electricity to pass through it.
Why might there be a charge in temperature when electrical current is passed through a conductor?
If the conductor has any resistance at all, then some energy is lost from a current flowing through it. Since energy is never destroyed or caused to disappear, the energy lost from the current must go somewhere. Almost always, it leaves the conductor in the form of heat. We encourage this process, bend it to our will, and use it to our advantage, in the design of toasters, hair dryers, space heaters, and incandescent light bulbs.
If an electrical current passes through a conductor what two things are generated?
If an electrical current passes through a conductor, there is an induced voltage (because no conductor has perfectly zero ohms), resulting in power dissipation, and there is a magnetic field, which can interact with other conductors in the vicinity of the first.
When current passes through a conductor what makes the conductor heat up?
The electrical resistance of the material. All materials have some electrical resistance except for superconductors.
How might you determine is it a conductor or insulator?
A conductor is when heat can pass through it. An insulator is something that heat does not pass through.
