The link between fluid dynamics and electron flow is incomplete and a bit on a stretch for most physicists but what better place to explore the topic than a blog? Laminar and Turbulent flow are two fluid concepts. Current and inductance are analogs. A turbulent flow that wraps back on itself stored energy in the same way as an induced curl field in a circuit. The telegraphers' equations specify the current as the series linear circuit elements R and L.
Viscosity is the propensity of the fluid to resist deformation. If an electron is injected into one side of a copper wire does one pop out the other side? Certainly yes though the turbulence of the route the electron takes is questionable. Now if you tried to push a Coulomb of electrons into the wire the capacitance specified by the telegraphers' equations would have to absorb all of the charge save the bleed off due to G.
In effect the ratio of R:G tells us something about how electrons behave in an electronic circuit. What is the ratio of electrons that push through to the load vs those that end up back at the electromotive force source having not delivered energy to the load. The probability that the electron will not deliver energy to the load is R:G.
