Jim, i think it would be better to refer books mentioned by Maverick. We may get a clear picture there. And here are some links which might be helpful http://www.youtube.com/watch?v=IMoJUqDlSQs"
No, I'm not at all going outside of simple Classical Mechanics. I'm just trying to explain the original poster about the derivation of F=m*A. When going by Newton's second law we'll get a relationship between F and m*A of the form F=K*m*A (where k is a constant). Take any value of K and define...
Let all the vectors be represented with capital letters and their magnitude by lowercase letters.
Let the "gorce" be G
and let G = [(m*A)^2]*[(m*A)/(m*a)] (the latter term is the unit vector in the direction of A)
Now, to find the net gorce of two gorces G#1 and G#2 we have to use a vector...
I'm getting your idea. Its just our understanding of "Force", a push or pull. But, the universe has got not nothing to do with our understanding. So, by common sense yes, if you double the force m*a gets doubled. But, its not at all necessary to have a linear relation between m*a and force. I...
What is required is the understanding of the "Force". In the scope of classical mechanics, the law F=ma is absolutely precise and I think not an approximation. Instead of trying to find out what acceleration is required for a particular extension, why don't we have an extension of the spring...
There is something called diffusion current. The electrons diffuse into the p region which gives the current. But, my concepts are not clear enough so, not absolutely sure!
I'd try to refer the books you've mentioned.
But, could you please explain in detail about the contact potential and the junction potential and their sum. I think its the main point here. If I'll understand it, my problem would be solved.
Thank you so much.
I think you are talking about this picture
And I got the concept of the capacitors but, I don't see any analogy. Here, it is clearly shown that the two regions p and n are not at the same potential, the n is at a higher potential and the p at a lower one. So, there is a potential difference...
Thank you Bassalisk.
But, after the potential difference is gone i.e. the barrier potential becomes zero then the diffusion of electrons would start again since there is no electric field now that could oppose there flow.
Again, a pd would be created and it would lead to an another current of...
The lines of forces are very simple in this case.
Now you don't have to worry about the signs and angles here. Just simply use the formula for moving a charge through an electric field and you'll get it.
I hope this helps.
Thank you.
Hi friends, here's my question.
The two terminals of a PN junction are at different potentials so, if I connect a them with a wire i.e. short them, What would happen? Would the potential difference between the two ends becomes zero or what? As far I'm understanding, there would be a flow of...
Your understanding of the concepts appears to be absolutely fine.
When you apply a force to the moving object, you are performing work on the object so, its kinetic energy must increase but, at the same time frictional force is doing a negative work on the object or extracting the energy of...
