The charge distribution when a nerve is at rest.
No impulse being conducted, so membrane is not very permeable to POTASSIUM (K+) and even less permeable to SODIUM (Na+).
Active transport has to be used to pump K+ in and Na+ out.
More negatively charged ions on the inside of the cell so more positive particles are going to move in (attraction):
More Na+ on outside, K+ on inside
Membrane is positive on the outside, negative on the inside
Membrane is said to be polarized
-70mV- is the difference in charges (resting potential)
