The RC circuit contains an ideal voltage generator of electromotive force E, an ohmic conductor of resistance R, a previously discharged capacitor of capacitance C, and a switch K.
When switch K is closed at t = 0, the capacitor undergoes charging until the switch is opened at t = 40 ms.
Close K → current flows → capacitor charges → permanent regime
📐 Formula — For a series RC circuit, the charge satisfies , so the differential-equation constants are and .
