Hi, Iam doing time domain study for ground rod in uniform soil under electric currents domain. im applying impulse current of 8/20 micro sec to the rod but im getting linear voltage at terminal but i have to get same shape of voltage as like impulse current in order to calculate transient resistance. here im attaching those graphs. i hope anyone can solve my problem. thanks in advance

If the current is not proportional to voltage the system cannot be described by a (linear) resistance.

The correct model MIGHT be a combination of L,C, and R, which might all be nonlinear. What's the physics of the problem?
