    Is there any free circuit simulation software out there like Multisim

    Have you tried TINA? I think you can get a few free student edition simulation softwares which are pretty good.

    Yenka is very basic but helps you to learn, but you need to specify what exactly you want it to do and to be honest nothing other than simple learning based simulators are going to be free.

    Good stuff like Multisim etc cost alot of money for a reason.

    Free good stuff: NL5 :)
    Free for 20 components and less - should be enough to learn electronics, free 1 year student license - no limits.

    Linear Technology's LTSpice is very good, and very free, with no limitations.
    Link: http://www.linear.com/designtools/software/
    It comes with most of Linear Technology's components, with a variety of other components thrown in. You can add as many other components as you wish; just find/develop the SPICE models.

    There is a very active LTSpice group in Yahoo! Groups; lots of models and samples to experiment with.

    Circuitmaker Student is pretty good, but it's been obsolete for 10 years or more. Limited to 50 components, you can't add new parts or create macros, and it won't run on Vista or Windows 7 from what I understand. Basically, it's a dead end. Too bad, as it's an easy-to-use simulator with a pretty good set of features.

    You might as well start learning a product that does have active support, and will run on a large variety of operating systems.

    Texas Instruments has Tina-TI that's free, available here:
    http://focus.ti.com/docs/toolsw/folders/print/tina-ti.html
    It's basically a somewhat stripped-down version of Tina.

    However, I find the interface to be a bit more quirky than the LTSpice interface. I really haven't used it enough to be comfortable with it.

    SgtWookie, thanks! I downloaded LTSpice and after a little tinkering caught on to it. I'm wondering, though, how to draw a differential pair in the standard fashion. Do you know if there is a way?
