Series shunt amplifier - How to evaluate the output resistance using pspice ?

Hi,
I cannot open your file, what did you use to create it.??

Could you post a circuit diagram of the shunt circuit.??
 
hi,
I use LTSpice.

For simple check I would measure the 'EMF' Vout voltage of the OPA [ with a light load, say 47K] and then use a 1K load resistor and remeasure the Vout of the OPA.

The drop in Vout at the measured 1K load current is Rout.
 
Hi, what do you mean by OPA ? And where do you connect 47K ?

The 741 is an OPerational Amplifier.

The loads would goto from the output pin of the 741 to 0V.

EDIT:

Look at page #5 of this pdf.
