Resting membrane potential of a neuron is about -70mV which means that the inside of the neuron is 70mV less than the outside. There are more k and less NA+ inside and more NA+ and less K+ outside.

What do you mean by resting membrane potential?

The resting membrane potential of a cell is defined as the electrical potential difference across the plasma membrane when the cell is in a non-excited state. Traditionally, the electrical potential difference across a cell membrane is expressed by its value inside the cell relative to the extracellular environment. [

What happens at resting potential?

Resting potential, the imbalance of electrical charge that exists between the interior of electrically excitable neurons (nerve cells) and their surroundings. ... If the inside of the cell becomes less negative (i.e., the potential decreases below the resting potential), the process is called depolarization.
