Two capacitor paradox

There are several alternate versions of the paradox. One is the original circuit with the two capacitors initially charged with equal and opposite voltages + and . [4] Another equivalent version is a single charged capacitor short circuited by a perfect conductor. In these cases in the final state the entire charge has been neutralized, the final voltage on the capacitors is zero, so the ...

Capacitor in Electronics – What It Is and What It Does

Learn what a capacitor is, how it works, and what it does in various electronic circuits. Explore the different types of capacitors, their properties, applications, and safety precautions.

Why is the capacitor short-circuited in this example?

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. The other two capacitors are in series, hence that:
