Characteristics of membrane potentials |
Number of charged molecules and ions inside and outside of cell nearly equal Concentration of k+ higher inside than outside cell ,NA+ higher outside than inside At equilibrium there is very little movement of K+ or other ions across plasma membrane |

Describe resting membrane protential |
K+diffuse out of the cell because there is greater concentration of k+ inside than the outside cell K+ move into the cell because positively charged ions are attracted to the negatively charged proteins and anions The resting membrane potential is established when the movement of K+ out of the cell is euq to their movement into the cell |
