The static resistance is DC resistance of the diode.
Rs=Diode DC voltage/diode DC current
From the table, the static resistance at source voltage of 5 V is,
Rs=Vd/Id
=4.981/(1.78926*10^(-9))
=2. 7838*10^9
=2. 7838 G ohm
The static resistance changes at each point of i-v characteristics.
The dynamic resistance is the ac resistance of the diode.
Rd=change in diode resistance/change in diode current
=(4.49-0.48)/(1. 78926*10^(_8)-1. 98807*10^(-9))
=2. 5213*10^8
=0.2513 G ohms
