Note that as the frequency ω → 0 the quantity Xc goes to infinity which implies that the capacitor resembles an open circuit . As the frequency becomes very large ω → ∞ the quantity Xc goes to zero which implies that the capacitor resembles a short circuit. Capacitors connected in series and in parallel combine to an equivalent capacitance.
As soon as the capacitor is short-circuited, it starts discharging. Let us assume, the voltage of the capacitor at fully charged condition is V volt. As soon as the capacitor is short-circuited, the discharging current of the circuit would be – V / R ampere.
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:
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.
A capacitor is typically constructed as shown in Figure 5.1. When a voltage v is applied, the source deposits a positive charge q on one plate and negative charge –q on the other. where C is the constant of proportionality, which is known as the capacitance of the capacitor. Unit for capacitance: farad (F). two plates.
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).

Introduction to Capacitors, Capacitance and Charge
When used on DC supplies a capacitor has infinite impedance (open-circuit), at very high frequencies a capacitor has zero impedance (short-circuit). All capacitors have a maximum working DC voltage rating, (WVDC) so it is advisable to select a capacitor with a voltage rating at least 50% more than the supply voltage.
