If we assume that a capacitor in a circuit is not initially charged, then its voltage must be zero. The instant the circuit is energized, the capacitor voltage must still be zero. If there is no voltage across the device, then it is behaving like a short circuit. We call this the initial state. Thus, we have our first rule regarding RC circuits:

6 FAQs about [Capacitor circuit diagram short circuit]
Are capacitors a short circuit?
In fact, that's exactly what you do. Capacitors are only short circuits when you consider the "small signal" component after you found the DC linearized point. So capacitors are open when considering the DC component, then shorts (or at least small negative imaginary impedance) when solving for the non-DC small signal response.
What does a short circuit mean in real life?
In "real life", a circuit diagram would not normally include a permanent wire connecting both ends of a capacitor. A short circuit here means that there is no resistance (impedance) between the two terminals of the shorted capacitor. The vertical wire drawn next to the vertical capacitor shorts the two terminals of the capacitor.
Why are capacitors used in small-signal analysis?
But when studying the circuit's response to AC signals (small-signal analysis), capacitors play a vital role in the circuit's behavior. Treating them as open circuits during this analysis would result in an incorrect representation of how the circuit behaves in the presence of AC signals.
What happens if a capacitor is shorted?
The vertical wire drawn next to the vertical capacitor shorts the two terminals of the capacitor. Any current flowing through this circuit segment will flow through the vertical wire and completely bypass the vertical capacitor due to the short. This means you can ignore the shorted capacitor -- it has no effect on the circuit.
Why does a capacitor have a short terminal?
By having their shorted terminals, the voltage thereof is zero (more precisely, the potential difference between them), so that this element is not operational in the circuit, and can be removed for analysis. The other two capacitors are in series, hence that:
What is a capacitor and how is It measured?
Capacitance represents the efficiency of charge storage and it is measured in units of Farads (F). The presence of time in the characteristic equation of the capacitor introduces new and exciting behavior of the circuits that contain them. Note that for DC (constant in time) dv signals ( = 0 ) the capacitor acts as an open circuit (i=0).
