Sometimes it is better to see one time than try to imagine things – especially in electronics. When designing something in electronics, it is probably the best way to take some circuit simulator and make a simple model see how it works before putting it into real worlds design. If you want to create complex circuit simulations, you probably should choose professional Spice based electronic circuit simulation tools. But what if you need a simple “pocket-sized„ simulator that would remind you of simple basics of how circuits work, how current flows in one or another situation. For this, you should try this Java-based circuit simulator.
