hi all. does anyone know of a free/demo version of a circuit simulator to confirm my answers to problems? google directed me to 'topspice demo' but i found that it more intended for professional electrical engineers.

gui preferred

thanks

Be advised: free software is sometimes worth what we pay for it.

 

This is a 30 day trial student edition by National Instruments. You could try this too.
