resist.cone {breakage} | R Documentation |
Calculates the resistance of a truncated conical volume of material of known resistivity.
resist.cone(l, r1, r2, rho = 51)
l |
Length of the truncated cone, in microns. |
r1 |
Radius of one end of the truncated cone, in microns. |
r2 |
Radius of the other end of the truncated cone, in microns. |
rho |
Resistivity of the conductive material, in ohm centimetres. The default value of 51 ohm cm corresponds to a 150 mM solution of KCl. |
Calculated resistance, in ohms.
A NaN
result will be produced if r1==r2
