Software to help learn about AC circuits

[AndyW]

I'm a physics student studying AC circuits at university at the moment. To help in my understanding, I'm looking for an application which allows me to construct a circuit and simulate it working, and make measurements. Something which covered basic LRC circuits would be a start.

I use Mac OS X, but I'm also able to run Windows apps under Virtual PC if need be.

Does it need to be free?

I use orcad's pspice. You can get a trial version here:
