The example of non-ohmic resistance is:
Let Fpp, Fpn and Fnn denote the magnitudes of the net force by a proton on a proton, by a proton on a neutron and by a neutron on a neutron respectively. Neglect gravitational force. When the separation is 1fm:
- Fpp > Fpn = Fnn
- Fpp = Fpn = Fnn
- Fpp > Fpn > Fnn
- Fpp < Fpn = Fnn
