Jelc.simulator 

Jelc.Simulator is a full electronic circuit simulator for electronics
students and teachers.

Build the circuit with your finger, wire it up and simulate. The current
flows through the wires as particles, the lamp lights up and the motor
spins - and underneath there is a real engine: DC operating point,
transient with a built-in oscilloscope (cursors, Vpp, RMS, frequency)
and Bode plots.

57 components, including the power electronics most simulators leave
out: SCR, TRIAC, DIAC, IGBT, optocoupler, transformer and a relay with
real coil physics. Plus 52 guided examples, 24 calculators and warnings
that teach.

10 languages. 100% offline. Light enough for a school netbook.

Rather not draw it? Jelc.Builder is optional: type "a
common-emitter amplifier" and it hands you the circuit, ready to open in
the simulator.
