Capacitor Transient Response | RC and L/R Time Constants
When the switch is first closed, the voltage across the capacitor (which we were told was fully discharged) is zero volts; thus, it first behaves as though it were a short-circuit. Over time, the capacitor voltage will rise to equal battery voltage, ending in a condition where the capacitor behaves as an open-circuit.

Transient response of RC and RL circuits
input: for example, a switch opening or closing, or a digital input switching from low to high. Just after the change, the capacitor or inductor takes some time to charge or discharge, and eventually settles on its new steady state. We call the response of a circuit immediately after a sudden change the transient response, in contrast to the steady state. A rst example Consider the …

Transient Behavior of Capacitor
Capacitor Transient Response Definition: The transient response of a capacitor is the period during which it charges or discharges, changing its voltage and current over time. Charging Behavior: When a voltage is applied, the capacitor charges, with the current starting high and decreasing to zero as the voltage across it increases.

8.4: Transient Response of RC Circuits
The key to the analysis is to remember that capacitor voltage cannot change instantaneously. Assuming the capacitor is uncharged, the instant power is applied, the capacitor voltage must be zero. Therefore all of the source voltage drops across the resistor. This creates the initial current, and this current starts to charge the capacitor (the ...

Capacitor Transient Response | RC and L/R Time Constants
The capacitor voltage''s approach to 15 volts and the current''s approach to zero over time is what a mathematician would describe as asymptotic: that is, they both approach their final values, getting closer and closer over time, but never exactly reach their destinations. For all practical purposes, though, we can say that the capacitor voltage will eventually reach 15 volts and that …
