Explanation:

For this course you should MEMORIZE THREE STANDARD NERNST POTENTIALS: Nernst potential for Na+ = +55mV, Nernst potential for Cl- = -65mV, Nernst potential for K+ = -90mV. (The Nernst potential is the voltage which would balance out the unequal concentration across the membrane for that ion.
