Can anyone help me

This circuit was in an exam last sunday and they were asking for Thevenin equivalent fo 12 ohms resistance. But it seems it is not working in this app. Can anyone explain me what am I doing wrong?

The 27H inductor is connected to your power supply and ground. Inductors theoretically dont have resistance and therefore you have created a path in which infinite current will flow. Just add a really small resistance in series with it.

Many moons ago when I was a smaller frequency Sine, in school we weren't allowed to use a calculator during a math exam. We were expected to show that we could make the calculations on our own. Using some device would be considered cheating. Isn't using a simulator in this fashion sort of like cheating too?..

L' induttore è in parallelo al generatore. Pertanto L facendo passare la tensione alternata cortocircuita il generatore a massa.

You cant calculate de thevinins equivalent of a circuit with complex components by simulation, the easiest way is using La place impedance of the compenents and simplify by writed hand

I was not trying to cheat, Im not allowed to use simulation software either. Im just trying to verify what I did during the exam.

Dont the inductors choke off the path of current?

try changing first the inductor bad place for the circuit performance

put one capacitor in series with the inductor

We're you given this circuit, then asked to calculate the Thevenin equivalent, or were you given 12 ohms, then asked to design the circuit? Either way, take a look at this web page - http://en.m.wikipedia.org/wiki/Th%C3%A9venin%27s_theorem#Example

You need to be more specific with the question, if this is the amount of information they gave you for exam you need to take your exams some where else.
