MultiSim is a great product to simulate electronic circuits. 
Many see it as the leader in simulation.
It allows you to simulate:
- resistor networks
- simple circuits
- DC / AC circuits
- Capacative / Inductive
- Transistors / Op Amps
- Digital logic
- and much more!!!
It also has real on the screen test equipment that is amazing. Just like having the real scope or meter on your desk!
