The concentration of k+ within a cell is required to be than the external concentration

K+ ion concentration is high inside the  cell under resting membrane potential.

Explanation:

Neurons generates electrical signals across its membrane called the resting potential. The resting potential is determined by the concentration gradient of ions and membrane permeability to ions.Therefore, in a resting neuron there are a concentrations gradient for Na+ and K+ ions across the membrane. The movement of ions towards the gradient through channels . The ions' movement create a resting potential by separating its charge.
