Initial charge on capacitor formula
WebbSince there is initially no charge Q on the capacitor C, the initial voltage V c (t) is V c (0) = Q/C = 0/C = 0 The capacitor behaves initially like a short circuit and current is limited only by the series connected resistor R. We check this by examining KVL for the circuit again: V s - i (t)R - V c (t) = 0 Webb7 apr. 2024 · Now when the switch is closed, the time begins at t = 0 and current begins to flow into the capacitor via the resistor and charge starts accumulating on the …
