Detailed explanation-1: -When the potential difference across the cell membrane is at rest, it is known as Resting Potential. The resting potential of neurons is about −70 mV which usually ranges between −60 mV to −85 mV. This resting potential is maintained by active transport as well as passive diffusion of ions.

Detailed explanation-2: -In humans this is said to be around-70 mV. This means that the inside of the cell is negatively charged in comparison to the outside. Resting membrane potentials are maintained by two different types of ion channels: the sodium-potassium pump and the sodium and potassium leak channels.

Detailed explanation-3: -The value of the resting membrane potential varies from cell to cell, and ranges from about-20 mV to-100 mV. For example, in a typical neuron, its value is-70 mV.
