When a neuron is inactive, its charge or resting potential is -70mV. The resting potential is a stable state created by polarization, whereby a different electrical charge exists on either side of the cell membrane due to the relative presence of negative or positive ions. When the neuron is at rest the concentration of negatively charged ions is slightly greater inside the cell membrane.
