Why is the resting potential in a neuron typically around -70 mV instead of being equal to the equilibrium potential of K+ (~-90 mV)

What would happen to the typical neuronal membrane resting potential if the extracellular concentration of K+ was increased?
The resting potential would become more positive
A membrane potential is the difference in electrical charge between
The inside and outside of a cell
