Conductance Definition and 57 Threads

I know the following ion/inside cell/outside cell Cl- 5mM 150 mM K+ 130mM 5mM Na+ 20mM 140mM Ca2+ 10^-4mM 2mM How would I find the reversal potential for conductance equally permeable to sodium and potassium? How do I find the reversal potential for a conductance equally permeable to...

Hi All, While going through quantum conductnace derivation, I got stuck by an integral. I = ((e*(h/2pi))/(m*pi)) Integral from 0 to infinity dt / ( exp (((((h/2pi)^2 * t)/(2*m)) - Ef) / kT)) + 1) The answer is I =...

I'm using Excel to work out the overall u-value for a wall consisting of several layers. To do this the following formula is used: U = {1 \over {{1 \over {\alpha _{outside} }} + {{t_1 } \over {\lambda _1 }} + ... + {{t_n } \over {\lambda _n }} + {1 \over {\alpha _{inside} }}}} It is...

Hi, I'm doing a project on mesuring the conductance of flames, but I need a lot more physics to back up my theory. I'm pretty sure that the Boltzmann factor is involved, however I can't link the two items together. The experiment so far has worked, by using a bunsen burner to burn the salts...

HI, I'm carrying out an experiment involving 2 "nanowires" of gold to investigate the quantisation of conductance. Does anyone know of any websites/papers the delve into the fundamentals?. Most papers I have read just go on about STM techniques Thanks The One

I'm wondering why coaxial cable would be characterized by conductance per unit length but not resistace per unit length Thanks for all yall's help, again :smile: Philip

I have this question whihc is confusing me on Conductance. The Question is Paper uniformly coated with graphite can be electrically conducting. A strip of the coated paper is 10mm wide and 250mm long has a resistance of 2KO (ohms). Sggest dimensions for a strip with conductance 1mA V-1 (little...
