Edit the circuit and select Solve circuit to calculate voltages, branch currents, power and residuals.
Project JSON preserves the electrical model, analysis settings, presentation units and schematic layout. Solver results are recalculated after import.
Model JSON contains electrical data. After import, the schematic layout may be recreated automatically.
Positive branch current follows the displayed direction. Power uses the passive sign convention: positive means absorbed power and negative means generated power.
