Would it possible to add the OHMIC RESISTECE to the inductor?

What if you add a resistance in series with the inductance? And how do you measure the active resistance of the inductor in the program?INDUCTOR OHMIC RESISTENCE 2022-278


In the Multisim program, this is done easily using a multimeter. On the left is the virtual inductance. Right real.

Ohmic resistence (R) and inductance (L) are two main parameters in a coil that affect its behavior in AC always. The way to calculate is to use de formula of impedance Z de L y R (Vectors at 90 degrees). If you do not want to take into the account the R, it is set to zero.

Z=squared root of R squared + omega squared x L squared, where omega is 2 x pi x frequency. Pythagoras.

The question you asked was how to put active resistance on inductance in the program.
I showed. As for calculations, this is another topic for discussion.
Inductance has many parameters. The basics you listed are for students no more. Inductors are different.

I sed "main parameters". Including both ( Inductance and Ohmic Resistence) now in the calculation is always better than nothing. Then there is always time for improvements if so considered and there is not more controversy on this point.

Usually in programs on virtual models of inductances, if the inductance has a small value, then the resistor is not set. On large values you need to set. There are many real chokes in Multisim. They already have active resistance inside. It depends on the call. turns, wire diameter and maximum current through the inductor.
There are no disagreements with you.INDUCTOR OHMIC RESISTENCE 2022-279

Then, Arcachofo, go ahead if you like and can. This would be the first step in the improvement.

In our program, inductance models work well. I made a diagram and showed it.
Inductive sensor for metal proximity to coils. Everything is well modelled. As in iron.

Para cuando aƱadir el parametro de RESISTENCIA OHMICA a los inductores y a los condensadores?
