Consider a neuron in which only potassium and chlorine ions are present in the cellular fluid. The concentrations for potassium are  mM and   mM. The concentrations for chlorine are   mM and   mM. The valence (ion charge) of potassium and chlorine ions is +1 and -1, respectively. Assume that the effective resistances for the potassium and chlorine channels are 13.0 MΩ and 5.00 MΩ, respectively. Calculate the equilibrium membrane potential for this neuron.

Beskou ’n neuron waarin daar slegs kalium en chloor ione teenwoordig is in die sellulêre vloeistof. Die konsentrasies vir kalium is   mM en   mM. Die konsentrasies vir chloor is   mM en   mM. Die valensie (ioon-lading) van kalium en chloor ione is +1 en -1, respektiewelik. Aanvaar dat die effektiewe weerstand van die kalium en chloor kanale is 13.0 MΩ en 5.00 MΩ, respektiewelik. Bereken die ekwilibrium membraan potensiaal vir hierdie neuron.
