Learn MoreA short circuit here means that there is no resistance (impedance) between the two terminals of the shorted capacitor. The …
Learn MoreAs capacitors store energy, it is common practice to put a capacitor as close to a load (something that consumes power) so that if there is a voltage dip on the line, the capacitor can provide short bursts of current to resist that voltage dip.
Learn MoreYou can think of shorting a charged capacitor like you would shorting a battery. When you short a storage device the only resistance in the circuit is the tiny resistance of the wire and the ESR (Equivalent Series Resistance) of the device itself. Assuming a perfect short, the current would be limited only by the ESR which tends to be very low.
