Definitely possible, e.g. in case of broken MLCC, altough open circuit is more likely. PCB shorts are possible as well. You can try to locate the short by supplying a limited current to the board (e.g. 1-2 A, whatever applicable) and measure trace/plane voltage drop with a sensitive multimeter.
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of multiple capacitors that are in series with a voltage source, as shown in Figure 8.2.11, the voltage will divide between them in inverse proportion. In other words
A 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.
As the frequency becomes very large ω → ∞ the quantity Xc goes to zero which implies that
I question the authoritative statements disparaging use of the terminology,
I question the authoritative statements disparaging use of the terminology, "short circuit" to describe the initial charging of a capacitor upon application of a voltage to a discharged capacitor. While the term, "short circuit" is only applicable for the initial microseconds or milliseconds or seconds after application of the voltage source
In a circuit, a Capacitor can be connected in series or in parallel fashion. If a set of capacitors
A capacitor is charged up to 200–500 V and discharged into a xenon gas–filled tube. Before handling capacitors or working on circuits where capacitors are used, it is a sensible precaution to ensure they have been
A capacitor acting as an HF short circuit must have low lead and PC track inductance, so each supply capacitor must be located very close to the two terminals of the IC it is decoupling. It is also important to choose capacitors with low internal inductance–usually ceramic ones.
A capacitor is neither an open circuit nor a short connection; it is a "duplicating voltage source" (a "voltage clone"). Imagine the simplest
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. Let''s first consider the parallel
Any 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.
Strictly speaking, a capacitor is not a short connection since its terminals are separated by an insulator. It rather behaves as a short
Find the rms current flowing in an AC capacitive circuit when a 4μF capacitor is connected across a 880V, 60Hz supply. In AC circuits, the sinusoidal current through a capacitor, which leads the voltage by 90 o, varies with frequency as the capacitor is being constantly charged and discharged by the applied voltage.
Capacitor in Parallel Circuit . When you connect capacitors in parallel, then the total capacitance will be equal to the sum of all the capacitors capacitance. Because the top plate of all the capacitors are connected together and the bottom plate also. So, by touching each other the effective plate area is also increased. Therefore, the capacitance is proportional to the ratio
The capacitor bank in delta connection can be utilized for high voltage however it is not achievable sometimes as in delta connection; the complete phase voltage is given across every capacitor while in star type connection, it is lesser as compared to applied phase voltage across the capacitor. So, 3 phase capacitor bank wiring diagram using two connections is discussed
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. Both they - a piece of wire and a discharged capacitor (at startup), have zero voltage drop across themselves; so the current is maximum.
In a circuit, a Capacitor can be connected in series or in parallel fashion. If a set of capacitors were connected in a circuit, the type of capacitor connection deals with the voltage and current values in that network. Let us observe what happens, when few

A capacitor is neither an open circuit nor a short connection; it is a "duplicating voltage source" (a "voltage clone"). Imagine the simplest capacitive circuit - a capacitor connected to a DC voltage source. The capacitor is charged to the source voltage and no current flows in the circuit because two sources of equal but opposite voltage are
Takeaways of Capacitors in AC Circuits. Capacitors in AC circuits are key components that contribute to the behavior of electrical systems. They exhibit capacitive reactance, which influences the opposition to current flow in the circuit. Understanding how capacitors behave in series and parallel connections is crucial for analyzing the circuit

Exploded electrolytic capacitors: Short circuits or reverse voltage conditions can cause electrolytic capacitors to heat up, build internal pressure, and rupture. Fig 2: A burnt capacitor can lead to damaged PCB. To summarize the key differences in the open circuit vs short circuit comparison, consider the following table: Characteristic. Open Circuit. Short
(b) Q = C eq V. Substituting the values, we get. Q = 2 μF × 18 V = 36 μ C. V 1 = Q/C 1 = 36 μ C/ 6 μ F = 6 V. V 2 = Q/C 2 = 36 μ C/ 3 μ F = 12 V (c) When capacitors are connected in series, the magnitude of charge Q on each capacitor is the same.The charge on each capacitor will equal the charge supplied by the battery. Thus, each capacitor will have a charge of 36 μC.
