What quality must the charge density on the surface of a conducting wire possess if an electric field is to act on the negatively charged electrons inside the wire?
non uniform
How electric iron become hot when electric current passes through it?
The electrons in the current have a lot of energy due to the tiny electric force on each one and the very large number of electrons involved. As they move from atom to atom in a metal conductor, some of this energy redistributes to the metal atoms. This energy causes the conductor atoms to move faster, which means they get hotter, and the heat flows to the surface of the iron.
What device gives off electrons when light shines on a metal surface?
There is the photoelectric effect, which is the process that emitts electrons from a metals surface when light of a certain frequency shines on the surface. In the metal, the nuclei are surrounded by electrons, so when the incoming electrons strike the surface, they pull apart from the electrons of the metal because of how like charges detract from each other.
What are some three basic features of an electric circuit?
basically electricity rules the world through electrons...it creates the deficiency of electrons in an object(conductor1) which in turn when touched with the other conductor2 results the flow of free electrons from conductor2 to conductor1..analogous to chemical reaction. the earth surface contains a variety of free electrons moving randomly.. the high voltage line when touches earth, the free electrons start flowing from earth to the high voltage line with a very large number of electrons and high speed.. if the line is thick(valuable size) and if there is some resistance to the flow of electrons then there would be no problem of line breaking but otherwise high speed electrons in very short duration of time when passes through a very low capacity conductor supporting less number of electrons to flow through will heat up the connecting(touching) point of conductor (analogous to welding) and will break it.. any problem..... engr shahid shahid_668@yahoo.com thanks
What is the resulting charge of a surface that gains electrons?
Electrons have a negative charge. Therefore, an atom having extra electrons is a negative ion.
A shortage of electrons on the surface creates an electric?
charge
What does a shortage of electrons on a surface create?
Static.
A shortage of electrons on surfaces create what kind of charge?
A shortage of electrons on the surface create positive charge. Because aall bodies in nature remains electrically neutral. But we know that electrons are negatively charged particles. It means if there is deficiency of electrons at any surface there would be positive charge. Which means electrons are less than protons which are positively charged particles and hence causes positive charge on surface.
How can Metal ions be electroplated onto a surface using an electric current?
electrons. Electrons are the only charges free to move in a metal.
How does the ground reduces the noise in electrical circuits?
A grounded metal shield that is around a signal wire prevents outside electric fields from reaching the signal wire. This is because electrons are free to move in a metal and the electrons in the metals surface move in response to the outside electric field. Below the metal surface the electric field is canceled by the field created by the electrons that have been drawn to the metal surface by the outside field, which is the noise source. Since the signal wire is within the metal cage it does not receive the noise.
Why surface of electric machine are made smooth?
The surface of electric machine are smooth why
What is maximum and minimum electric flux?
As we know that electric flux is the total number of electric lines of forces passing through a surface. Maximum Flux: Electric flux through a surface will be maximum when electric lines of forces are perpendicular to the surface. Minimum flux: Electric flux through a surface will be minimum or zero when electric lines of forces are parallel to the surface.
What quality must the charge density on the surface of a conducting wire possess if an electric field is to act on the negatively charged electrons inside the wire?
non uniform
What is the emission of electrons from a metals surface?
the external energy given to electrons,thier kinetic energy increases.thus electrons move from metal surface
How does the depletion region in field effect transistor increases when forward biased?
Because the bulk charge and surface charge interacting with electric field (forward bias) creates the depletion region.
What microscope creates an image of the surface?
SEM
