Hello, is there a way to get the Req (equivalent resistance ) and the Rth (Thevenin Resistance) using this software?

If possible, can an example be simulated to understand the concept? Thanks

You could try using some of the theory method: (1) replace V source(s) with short circuit(s), (2) attach new source (eg 1V) to the load terminals, (3) simulate and note the source current: R(th) = V/I

A little indirect, but hopefully still some use?

@horaciopena,

You might like to have a careful look through these examples:
