Total leak conductance (a.k.a. input conductance) and voltage attenuation in a passive 2-compartmental model.

Definitions and example values: dendritic leak gdL = 1, dendritic inhibition gdI = 3, axial conductance ga = 4, somatic leak gsL = 6, and somatic inhibition gsI = 3. The following expressions were obtained by applying laws of electrical circuit analysis to nodes d and s in Figures 4 & 5 (viz. impedances in parallel & series, Kirchhoff's current law).
