Coulomb for Linux

Electronic circuit simulator

Overview

Coulomb is an electronic circuit simulator designed for Linux users.

It fits well for science and education purposes, helping users understand how circuits work by letting them build and test circuits on their computer.

With Coulomb, you can draw any circuit you want using common devices like resistors, batteries, inductors, capacitors, diodes, and more.

The app allows you to plot voltage and current over time, so you can see how your circuit behaves.

It has a clean and easy-to-use dark mode interface that helps reduce eye strain, and you can save your circuits to work on them later or load previous projects.

The software supports a good range of basic devices such as resistors, batteries, current sources, AC voltage sources, inductors, capacitors, diodes, and Zener diodes.

This makes it useful for students and hobbyists who want to explore electronic circuits.

There are some current limits to keep in mind.

Coulomb struggles with circuits that include non-linear devices because the backend can't solve their behavior accurately yet.

Also, due to the way inductors and capacitors are modeled, you cannot place two inductors in series or two capacitors in parallel right now.

The developers have plans to improve these features in the future.

Overall, Coulomb offers a safe and straightforward tool for Linux users interested in simulating electronic circuits, especially those looking for an educational and visual way to learn electronics basics.

Pros

  • Allows drawing arbitrary circuits and plotting voltage and current against time.
  • Supports save/load functionality and dark mode with a beautiful UI.
  • Includes a range of common devices such as resistors, batteries, inductors, and diodes.

Cons

  • Struggles to solve circuits containing non-linear devices due to backend limitations.
  • Cannot place two inductors in series or two capacitors in parallel due to modeling constraints.
