If you can find the book written by Hille B. or any medical physiological
book, you will find the answer. According to the Nernst Equation (Nernst
1888), Ek=RT/ZF*ln[K]o/[K]i, an increase in the extracellular K+ concentration
will cause less negative membrane potential (depolarization)! Remember at the
resting conditions, most cell membrane only permeates K+ through membrane, not
Cl-, Ca2+ or Na+.
