can someone tell me how to calculate equlibrium potential of an ion.its bit confusing.

nearsnt equation= -2.3RT/ZF (C1/C2). BRS has explained it well

It's probably just a typo, but you need to take the log of the ratio of concs (outer/inside) (and a positive 2.3 as well if you take C1 as outside and C2 as inside concentrations). If you take the natural log, omit the 2.3.
E = 2.3RT/(zF)*log(Cextracellular/Cintracellular)

i found nerst equation bit hard to rember. but i lernt from my notes dat u gota find equlibrium potential by just taking concetration forces plus elctrical forces wid vector diagram on each ion indivdullay and if the diference b/w inside and outside ion 10 fold so consider the ion wid greatest ion wid 60 mv. and for elctrical forces u have to think abt theire directions.. well i prefer to look into kaplan physiology they explained there well wid examples...
