Circuit simulator

Hello,I'm looking for a virtual circuit simulator with Video/Audio to learn electronics.
For eg. Diode is converting the AC to DC. So the simulator should show the current directions of the circuit before applying AC to the diode &after the output from the diode.ANd the capacitor will filter the noises & so it should give the sound effect of the pre/post processes. ANd Ofcourse it should have the major components within that & allow us to edit the values. And probe points to measure the values.

Plz let me know is there any tool available like this. Thanks!!!

Try these circuits simulators

1. circuits-cloud http://circuits-cloud.com/

Here is something I found interesting, http://lushprojects.com/circuitjs/ it shows the current flow. Hope this helps.
