I am trying to find the load regulation using zener diode for this i need variable load resistance. i have added a device R_variable but i am find difficult to add value and do the simulation.
Please suggest any workable soultuion to find the variable R during simuation
Sorry for the delayed response due to technical problems. Please use the normal eSim_diode ONLY. In the KiCad to Ngspice conversion tab, add the model file for the Zener diode. It will work fine.
For changing the Resistance value, right-click on the resistor->Edit Component-> Value->Give the desired value of the resistor, e.g. 1k->Click on OK button.
Please see the Spoken Tutorial videos to understand circuit simulation in eSim: https://spoken-tutorial.org/tutorial-search/?search_foss=eSim&search_language=English
