resist.cone: Calculate resistance of a truncated conical conductor

Description

Calculates the resistance of a truncated conical volume of material of known resistivity.

Usage

resist.cone(l, r1, r2, rho = 51)

Arguments

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.

Value

Examples

# resistance of truncated conical segment 30 microns long, with end radii 50nm and 500nm
# filled with solution of resistivity 64 ohm cm
# converting result from ohms to megohms for readability
