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:
How does a capacitor work?
A capacitor is a device that, when connected to a DC power source, has an interesting behavior. See the diagram below. When the “A” switch is closed, the current “I” suddenly increases to its maximum value (such in a short circuit) and has the value I = E/R amps.
What happens to a capacitor when a switch is closed?
When the switch is closed the time begins at t = 0 and current begins to flow into the capacitor via the resistor. Since the initial voltage across the capacitor is zero, ( Vc = 0 ) at t = 0 the capacitor appears to be a short circuit to the external circuit and the maximum current flows through the circuit restricted only by the resistor R.
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.
Can a capacitor be charged instant?
The charging of a capacitor is not instant as capacitors have i-v characteristics which depend on time and if a circuit contains both a resistor (R) and a capacitor (C) it will form an RC charging circuit with characteristics that change exponentially over time.

The smaller the capacitor the less energy is needed to charge the capacitor. But there is less energy stored in a small charged capacitor than in a large charged capacitor. It boils down to only being able to get out almost as much energy as you put in. To charge a bigger capacitor faster you need a generator with more output power.
