Derive expression for the restriking voltage

WebRearranging the equation gives us the capacitor voltage: V c (t) = V s - i (t)R Initially V c (t) is 0, however as current decreases, the voltage dropped across the resistor R decreases and V c (t) increases. After 4 time constants, it has reached 98% of its final value. WebApr 15, 2024 · The practical calculation procedure: The capacitor has 50V initial voltage, but for t>0 it's connected to a voltage divider which outputs only 25V through 500kOhm Rt. Time constant = 1s and that's used for calculating how 50V initial Vc settles towards 25V. 50V decays off and at the same time the capacitor is charged to 25V.
