Capacitor: at t=0 is like a closed circuit (short circuit) at 't=infinite' is like open circuit (no current through the capacitor) Long Answer: A capacitors charge is given by Vt = V(1 −e(−t/RC)) V t = V (1 − e (− t / R C)) where V is the applied voltage to the circuit, R is the series resistance and C is the parallel capacitance.
The capacitor acts as open circuit when it is in its steady state like when the switch is closed or opened for long time.
And for the inductor it'll behave as a short circuit in its steady state and open circuit when there's a change in the current. Capacitor acts like short circuit at t=0, the reason that capacitor have leading current in it.
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.
When discussing how a capacitor works in a DC circuit, you either focus on the steady state scenarios or look at the changes in regards to time. However, with an AC circuit, you generally look at the response of a circuit in regards to the frequency. This is because a capacitor’s impedance isn’t set - it’s dependent on the frequency.
Capacitors act somewhat like secondary-cell batteries when faced with a sudden change in applied voltage: they initially react by producing a high current which tapers off over time. A fully discharged capacitor initially acts as a short circuit (current with no voltage drop) when faced with the sudden application of voltage.
