Consider the output of an optocoupler in series with a 27k resistor connected to a fixed voltage of 66V.
In LTSpice I am able to plot the current in this circuit as a function of the input signal. However I need the equivalent resistance value. In other words 66V divided by the current found. I can not find the way to do that in LTSpice.
I am able to transfer the plot data to Excell and handle it over there but it would be nice to solve the situation in LTSpice.
In short: Is there a way to modify the plot Y axis from current to resistance?
