The Falstad Circuit Simulator is not trying to compete with Multisim or LTspice . It is a unique pedagogical tool that prioritizes intuition over precision. For the first week of an electronics course, it is arguably more effective than any professional tool on the market. Users can modify circuits while the simulation is running
