This is false that Smaller neurons require more current to change their membrane potential.
A potential gradient known as membrane potential causes ions to passively migrate in one direction: positive ions are drawn to the "negative" side of the membrane, while negative ions are drawn to the "positive" side. Human life is impossible without membrane potentials. Over their membrane, every living cell maintains a potential difference. Simply said, differences in the concentration and permeability of significant ions across a membrane are what cause membrane potential.
A change in membrane potential results from a change in ion permeability. The membrane potential moves closer to the ion's Nernst equilibrium potential as permeability to that ion increases. The membrane potential is shifted away from the ion's Nernst equilibrium potential as permeability to that ion decreases.
The less probable it is that the arriving ions will collide with something that might cause them to bounce back, the bigger the axon's diameter of a neuron. Positive ions must continuously move away from the cell body in order for the action potential to exist, and this is made much simpler in a bigger axon.
