Why does a capacitor act as an open circuit under a DC
A capacitor connected to a voltage source in a steady state is charged to the voltage of the source. Thus, in the loop, it acts as an oppositely connected clone voltage source. As a result, no current flows, creating the
Capacitors | Brilliant Math & Science Wiki
If a circuit is driven by a battery, the battery will charge capacitors until the voltage across the capacitor perfectly opposes the voltage from the battery, resulting in an effective open circuit in which no current flows.
Why capacitor behaves as open circuit in DC?

6 FAQs about [Capacitor in open circuit state]
When does a capacitor act as an open circuit?
The capacitor acts as open circuit when it is in its steady state like when the switch is closed or opened for long time.
Why does a capacitor act like a short circuit at t 0?
Capacitor acts like short circuit at t=0, the reason that capacitor have leading current in it. The inductor acts like an open circuit initially so the voltage leads in the inductor as voltage appears instantly across open terminals of inductor at t=0 and hence leads.
What is the difference between a capacitor and a closed circuit?
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.
What happens if a capacitor is a short circuit?
(A short circuit) As time continues and the charge accumulates, the capacitors voltage rises and it's current consumption drops until the capacitor voltage and the applied voltage are equal and no current flows into the capacitor (open circuit). This effect may not be immediately recognizable with smaller capacitors.
What is the difference between a conductor and a capacitor?
Short Answer: Inductor: at t=0 is like an open circuit at 't=infinite' is like an closed circuit (act as a conductor) 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:
Why does a capacitor look like a short for no time?
Until they charge, a cap acts like a short circuit, and an inductor acts like an open circuit. When you turn on an ideal switch from an ideal voltage source, to an ideal capacitor you get some odd solutions, in this case infinite current for an infinitesimal time. So it looks like a short for no time.
