But why you can say that the voltage is fixed? In reality this isn't the case.
Also i still don't understand why the nernst potential isn't the voltagedrop, caused by moving ions. I mean you can't meausure potentials and i saw a meassurement, where you could see the the voltagedrop. Was this...
Im sorry, correct me if I am wrong but isn't that the same? Or you mean its a potential and not a voltage?
Im asking because I saw an experiment with exactly the example below for KCl and CaCl2. The voltage we meassure for KCl was 58 and for CaCl2 it was 29, the half.
Okay if i understand the...
Yeah it is a electrical neutral solution but i don't see how this effect the potential or the voltage...
I mean, the Ca+2 will drive to the side of less concentration and in case of chloride i thought i can't go through the membran, so it will stay on one side.
I understand what you write about...
Good evening,
I got a seriously problem at understanding the membrane potential for ions in a cell. Particulary, i don't understand the case for example for ions with a charge of 2 or higher. I take a look on two scenarios: If you got an ion like calium and got a concentration ratio of 1:10...
Yes that's the paper i read first and than i come to the one which i quote here :D the Problem is it doesn't help because it refers to the one i quote :( . Ist just the same just a bit shorter. i totally understand the Maths behind it (i think so), but not the Physics which he is complaining :(
mhmmm but it still not that what i meant...close but not the same...is it still the Right Explanation? And can you argue for the same with the 3D resistance, but here we have the Argumentation that you have an additional circuit in the bulk (because in the paper the author says in the 3D case...
ohhh god! i think i have it thank you sooo much. Because the totally resistance is smaller than the lowest, you will have smaller resistance if you have an additional spreading current, Right?
but just to make sure of that the author really meant this i just want to take a look in this paper...
I have a Question to the Independence of the probe distance for a four-probe-measurement technique. In a paper the author is argument that the resistance of a 2D shape is NOT dependent of the distance between the probe which measure the voltage drop, cause he says that the current spreading...
Hallo guys,Im kinda confused about something and hope you can help me. Let me introduce you to it.
we take a look on one Mechanismen to the spin hall effect, skew scattering effect. i just read that you can see this contribution only in the clean Limit. So that's really strange for me cause...
Hello there,
I don't really get the difference between the extrinsic or intrinsic spin hall effect or contribution. As i understand, in extrinsic you have spin scattering by impurities, so its the spin orbit interaction of the spin with its orbit, and this orbit is influenced by an impurity...
Yeah, XRR tells you something about roughness, i don't know what you meant with SEM or what does it gives you more or less an information, but XRR is way to see how unity is the structure.
What is an I-V Scan?
You meant a picture of the sample structure or of the measurement technique? Well i...
