RL calculator
Calculate time constant and inductive reactance.
How to use it
Start with the example circuit, change values in the properties panel, connect pins by clicking them, choose an analysis and press Run. The exact netlist used by the solver is always visible.
What is calculated locally
The project, netlist and simulation vectors remain in the browser. A Dedicated Worker performs the computation, while exports are created as browser Blobs.
The built-in solver covers linear RLC circuits and independent sources. Semiconductor symbols are parsed and checked, but accurate nonlinear device models require a separately verified ngspice WebAssembly build.
FAQ
Does this certify a physical circuit?
No. Simulation depends on models and assumptions and never replaces measurement or safety review.
Are files uploaded?
No project or netlist is uploaded by the application.
