The resting membrane potential is when the net flow of ions across the plasma membrane is zero. In humans this is said to be around -70mV[1]. Even resting potentials are very active as sodium and potassium ions are constantly being actively transported by the sodium-potassium pump, but some potassium ions leak back through the potassium ion leak channel.
