First-order model
The curve assumes an ideal capacitor, ideal resistor and ideal step source. Leakage and ESR are ignored.

Capacitor Charge & Discharge Simulator
Visualise first-order RC charging and discharging curves.
Loading the simulator…
Teaching model. This simulation uses ideal elements and a deterministic solver. It does not represent real transient behaviour, heating, tolerances or fault energy. Do not use it as a design or safety calculation.
Change R and C and compare the time constant with the plotted response.
