Editing Resting potential (section)

==Electroneutrality==

In most quantitative treatments of membrane potential, such as the derivation of [[Goldman equation]], '''electroneutrality''' is assumed; that is, that there is no measurable charge excess on either side of the membrane. So, although there is an electric potential across the membrane due to charge separation, there is no actual measurable difference in the global concentration of positive and negative ions across the membrane (as it is estimated [[#The number of ions involved in generating the resting potential|below]]), that is, there is no actual measurable charge excess on either side. That occurs because the effect of charge on [[electrochemical potential]] is hugely greater than the effect of concentration so an undetectable change in concentration creates a great change in electric potential. {{Citation needed|date=September 2014}}
