Customer ServiceYou can discharge a capacitor by simply connecting it to a circuit without a source, or you can short-circuit the poles of the capacitor using a conducting material. When do capacitors discharge? Capacitors discharge when another path in the circuit that allows the charges to flow to each other is created.
Customer ServiceStrictly speaking, a capacitor is not a short connection since its terminals are separated by an insulator. It rather behaves as a short connection with respect to the voltage drop across it. Both they - a piece of wire and a discharged capacitor (at startup), have zero voltage drop across themselves; so the current is maximum.
Customer ServiceKey learnings: Capacitor Definition: A capacitor is defined as a device with two parallel plates separated by a dielectric, used to store electrical energy.; Working Principle of a Capacitor: A capacitor accumulates charge on its plates when connected to a voltage source, creating an electric field between the plates.; Charging and Discharging: The capacitor

Customer Service$begingroup$ A current impulse (infinite di/dt) can only pass through a perfect inductor if the terminal voltage across the inductor is infinite. In a practical world, an inductor has self-capacitance and this means the impulse current bypasses the "magnetic" side of things and appears to pass through the inductor, but it doesn''t theoretically.
Customer ServiceA capacitor short circuit occurs when the two plates of a capacitor come into direct contact, bypassing the dielectric material between them. This results in a sudden discharge of the capacitor''s stored energy.
Customer ServiceAny element for which terminals are connected by a conductor, as the capacitor in the figure, is said to be shorted. 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.
Customer ServiceCapacitors use dielectrics made from all sorts of materials. In transistor radios, the tuning is carried out by a large variable capacitor that has nothing but air between its plates.

Customer ServiceIs capacitor short or open in steady state? Once the capacitor has been charged and is in a steady-state condition, it behaves like an open. This is opposite of the inductor. As we have seen, initially an inductor behaves like an open, but once steady-state is reached, it behaves like a short. For example, in the circuit of Figure 9.4.

Customer ServiceShorting of a capacitor refers to the process of connecting the two terminals of a capacitor together, effectively reducing the capacitance to zero. Why would someone want to short a capacitor? Shorting a capacitor is usually done for safety reasons, such as to discharge the stored electrical energy in the capacitor or to prevent accidental shocks.
Customer ServiceWhen a capacitor is charged by connecting it directly to a power supply, there is very little resistance in the circuit and the capacitor seems to charge instantaneously. This is because the process occurs over a very short time interval.
Customer Service(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.
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.
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:
Under this steady state condition its impedance seems to be infinite. This phenomenon can be better explained in time domain than in frequency domain. Strictly speaking, a capacitor is not a short connection since its terminals are separated by an insulator. It rather behaves as a short connection with respect to the voltage drop across it.
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.
