Understanding Short Circuits in Capacitors
So the wire "short circuits" the capacitor. Another way to look at it: Since the capacitor and the wire are parallel with each other they must have an equal voltage drop across them. If we assume the wire is a perfect conductor with zero resistance, the voltage drop across it is zero, leading to zero voltage drop across the capacitor as well.

Why is a capacitor considered a short circuit at start up?
If we use a capacitor that has a decoupling capacitor, so shunted to ground, then why for a DC source do we say the capacitor acts like a short at startup (t=0) thus having a high inrush but according to the top
Why is a capacitor considered a short circuit at start up?
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.
capacitors acting as short circuit | All About Circuits
While the term, "short circuit" is only applicable for the initial microseconds or milliseconds or seconds after application of the voltage source (depending upon the time constant of the circuit), the fact that the initial current is usually limited only by the stray inductance, source circuit resistance, and internal resistance of the capacitor qualifies the initial condition as a

psu.why & how to replace the dreaded capacitors in ATARI ST!
For normal power supply electrolytic capacitors, these come in ratings measured in µF (micro Farads). A replacement capacitor should have the same value. If you are unable to get the exact value, it normally does not cause problems if you fit a slightly larger value (if it will fit on the circuit board).
Differences Between Electrolytic Capacitors and Film Capacitors
Electrolytic Capacitors: Electrolytic capacitors generally have lower voltage ratings, typically ranging from 6.3V to 450V. Overvoltage can lead to dielectric breakdown and eventual failure. Their construction makes them more prone to short circuits if the oxide layer is damaged. Film Capacitors:

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.

Why does a capacitor act like a short-circuit during a current
$begingroup$ 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.

6 FAQs about [Are capacitors prone to short circuits ]
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 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.
Is a capacitor a short connection?
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.
Can a capacitor be the source of a short?
In case of wrong connection it can be a source of high current between supply and ground. Other source can be an ESD diodes in the IC, again in case of mismatched connection. yes today a capacitor (usually smd) can be the source of a short. it can be mlcc or tantalum, but mainly smd. I had a display power supply failure in an old VCR I had.
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.
What happens if a capacitor is not charged?
If at a given time t0 t 0 a capacitor is not charged, by definition, it has q(t0) = 0 q (t 0) = 0, hence v(t0) v (t 0) must be 0, even if some current in that instant of time is flowing. Therefore, at that instant, the capacitor is like a short circuit: current flowing, no resistance and no voltage across it.
