Why is heat produced in a wire when current is passed through it?

I am not sure what exactly happens at the quantum level; and it might be quite complicated. But you can imagine some electrons, that usually make up the current, bumping into atoms or other electrons, and losing their energy. That "lost" energy, of course, is converted into heat.

when current pass through a metal the metal resist the current so heat produces, if the metal resist the current more, more heat produces, if resist less, less heat produces. when current transmit from one place to another place by a wire some current loses due to resistence so while transmit the current less resistence metals are using.

How does heat through solid?
The process of conduction is how heat moves through solids. With solids, the heat energy is passed on by the atoms.
What is convection current in sport?
heat is produced as the air particles are disturbed and heat energy from transfered from food(chemical energy) also allows heat to pass through gas or liquid(any fluid.)
A fuse will melt if the?
A fuse is made with the material which offers high resistivity. When a large amount of electric current passes through the fuse, heat above the melting point of fuse is produced. Hence, the fuse melts.
What is a neutron stars' source of heat?
A neutron star no longer produces energy - it is a dead star. It will gradually get colder, until it stops emitting any significant amount of heat. Any heat the neutron star radiates is residual heat - heat that was produced earlier, either through fusion, or through the tremendous gravitational collaps that produced the neutron star.
How does heat move out from the inner core to the surrounding layers?
The heat is passed through conduction ,from one atom to another that is why the core is hotter than surface ;some heat is lost in space.
What source of heat does a halogen light use?
an electric current passed through it
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.
Does every conductor heat up when electric current is passed through it?
yes every conductor heat up fast
Why the water gets heated when current is passed through carbon rods in it?
The carbon rods have electrical resistance. Thisi causes them to heat when current is passed through them. The water gets heated by the carbon rods.
What is the two forms of energy that resistors can give off?
Heat energy and light energy when the current passed through them.
What may cause an electrical conductor to heat up?
An electrical conductor may heat up due to excessive current passing through it, which increases its resistance and generates heat. Poor connections, overloading, or inadequate conductor size can also cause heating. This can lead to a potential fire hazard if not addressed.
What happen to an electric current after it passes through each bulb?
There is a piece of filament in every light bulb, which has so much friction that when the electric current passes through it, heat energy is produced. This heat energy is then converted to light energy.
Why eddy current damping is not used in moving iron instruments?
because eddy current is produced by the heat produced in winding
On what factors does the amount of heat produced in an electric wire depend?
-- The resistance of the wire.AND-- The voltage between the ends of the wire.OR-- The current through the wire.
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.
What is the relation between the amount of electric current passed and the heat produced?
The relation is:P = I2RWhere:I is the current (for example, in amperes)R is the resistance (for example, in ohms)P is the power (energy per second) converted from electrical energy to heat. If the current is in amperes and the resistance in ohms, then power is in watts (equal to joules/second).
How does heat through solid?
The process of conduction is how heat moves through solids. With solids, the heat energy is passed on by the atoms.
