Can anybody please help!? I know it uses the equations above, but something is going wrong in the last step when I'm trying to calculate the number of channels and conductance...I know what the answers should be; number of channels is 3E6

 

 

Data:

 

bilayer area = 1.1E-6m2

bilayer thickness = 2.5E-9m

channel radius = 1.5E-9m

channel thickness = 2.5E-9

diffusion constant = 1.2E-9

dielectric constant = 2.3

change in energy (i.e U or sometimes E)

 

can anybody help please?

 

I think I am getting stuck when calculating the conductance and unsure what to divide by...

 

Please let me know if you require more info.

 

Thanks
