Thank you eq1 for the help and I will surely read the book from the link. But from what you wrote I have some small questions or doubts.
When here you say "given electric field" does the word given electric filed means the electric filed requires is fixed for a pn junction of given material...
Thank you phyzguy, yes I read wikipedia on this.But I am still not satisfied with the answer (not because answer is wrong but because I must be missing something).
I have the following issues with this.
(1) It is said to get the same electric field with the increased doping less space...
My question for now is as follows: Why does a high doping concentration causes a decrease in the thickness of depletion region.
Any help will be highly appreciated!
Thanks a bunch
Regards!
I am sorry I just did a little mistake in converting angles from trigonometry ratio, now I got the correct angle. 162° so to cover whole earth 2 satellites are not enough and therefore minimum of 3 must requires.
[The forum rules actually forbid giving help until that effort is shown]...
My question is, given that the height of geostationary satellite to be 35786 Km and radius of about 6378km determine the area covered by a geostationary satellite Or deteremine minimum number of geostationary satellites requires to cover whole earth.
Regards thanks a bunch :)
Thanks hilbert2 for the answer with rigorous concepts of QED. Form what Gene Naden endorse and what I could conclude from your post is that the answer to my very question in my first post of this thread is that the electron will do nothing with that energy and will not go to next excited state...
Thanks Gene Naden giving your opinion and I also think so :) however just need an answer from someone who can answer this with surety not a mere opinion.
Hello all,
I have a question. Consider an electron in a shell of an atom has energy as 1.0ev and in the next shell it energy should be 2.7eV and the further next level energy is let's say 3.1eV. Means an energy gap of 1.7eV is their between first and second level and an energy gap o 2.1 eV is...
Hello all,
I was going through study of gravitation of earth. The book teachs that gravity of earth is more near poles than at equator as earth is not perfect sphere rather radius of earth is lesser near poles larger at equator. A thought came in my mind that if the water at level goes also...
What is "that way" I would like if you write it in more open way instead of saying"that way", I mean what will you say how we treat infinitesimal small displacement to come up with definitions of torque and angular momentum as told by you?
Regards
Hello all,
First of all I want to mention what believe or result of concepts, do I hold about rotational motion especially about the angular velocity. I assume that unlike velocity angular velocity has to worked out from some point. I will begin with particle for this I assume that the question...
So should I say that finite angular displacements are neither scalars nor vectors(here risk is that my students will ask in what category are they fall and questions like what is the name of that category etc fall upon me :)) )
Or should I say it is controversial matter just remember that they...
Yeah that's where I need endorsement I mean I now agree that finite angular displacement doesn't obey commutation law I still don't feel confident in saying that, by not obeying commutation law by the finite displacements they are kept out of the category of vectors.
Thanks both of you, very well explained.
Though this has been explained very well I just need endorsement about the statement, that finite angular displacement is Scalar and infinitesimal small displacement is vector? Can I say it to my students or does this is a valid statement amongst the...
Hello all,
I am having hard time to know if the finite angular displacement really a scalar quantity?
In some books they say angular displacement when finite is Scalar and when infinitesimal small is Vector, with direction perpendicular to plane of circle government by right hand rule.
I...
Diamagnetic materials have their magnetic moment due to spin and there is no net dipole moment due to orbital motion of electrons. In any material having dipole moments due to orbital motion of its electron, many dipoles cling together in same orientation for reasons explained only by invoking...
Dear all, I know the sources of magnetic field are moving charges or varying electric field. I also know that subatomic particles(even neutron) have their own magnetic moment due to its quark and spin and their magnetic moment is explained by invoking quantum mechanics(though I don't know how...
Hello all,
I came to know that electric(electromagnetic in general) force between charge particles is mediated by photons. At first I just wondered what are photons doing here? I mean till what I know is that photons bundels of energy for em radiation and that they are massless but have...
Ok thats good. Can you suggest me some(or better only one best) book(s) to me for learning more about error analysis in measurement?
I have one another function( no so complex) where I need to write expression for error. Can I ask?
I know what is standard deviation, but what is standard error and Wolfram Mathematica things I don't know.
I would like if you could take me to the target point as easy as possible but if that's not possible unless I study special statistical methods than thing is different. In that case I...
Can you please elaborate I am not good at these statistics so that I can figure out the differences of details of statistical deviation and systematic deviation.
I really want to know it from the core. :)
Regards
This is giving me some thought but what if the rods are made not only in the same factories but also in the same mould under same conditions. I mean isn't it possible that they are identical?
Why?
Can you give me an example as it will be more helpful.
I am very happy to see you all helping...
