About

Coulomb is a simple and elegant circuit simulator.

Features:

  • Draw arbitrary circuits
  • Plot voltage and current of devices against time
  • Save/Load circuits
  • Dark Mode support
  • Beautiful UI

Available Devices:

  • Resistor
  • Battery
  • Current Source
  • AC Voltage Source
  • Inductor
  • Capacitor
  • Diode
  • Zener Diode

Problems:

- Circuits containing non-linear devices will most probably not be solvable, because the current backend is not good at dealing with non-linear systems, that's going to change though. - Due to the way inductors and capacitors are modeled you can't put two inductors in series, or two capacitors in parallel, that's also going to be fixed.

Permissions

1 permission weaken the sandbox. Flatsonar asks before installing.
