Figure 2c : Fig. 2a. circuit constructed in PSpice
A time analysis of any runtime outputs the current and voltage of the nonlinear component as following
(during actual work part names might be changed as a result of copy and paste process, which is usual working
in simulation medium and should be ignored ) :

In order to obtain the graphical solution (operational point current and voltage values) the following
□ I (V1) o V(E3:OUT+, E3:OUT-)
construction is contrived, where CCCS part allows copying the sweep current thus making two graphics drawn
in the same plot):
