Ghk equation rt/f
Web2 days ago · G–V relationships were derived from I–V curves by calculating G as follows: G = I/(V m − E rev) and fit with a Boltzmann equation; I is current, G is conductance and V m is membrane voltage. WebMay 7, 2024 · 1. The GHK voltage equation also known as just "Goldman equation" is always valid for determining the voltage at which the net current is zero, given internal/external ion concentrations and their permeabilities. This includes times during the action potential, though the result you get from GHK will be changing faster than the …
