When a capacitor with a charge of $q$ is discharged, a mass $m$ of rattlesnake gas is released through an electrolytic bath with acidified water. The mass of the substance released during electrolysis depends only on the passed charge. So, by discharging the capacitor through $k$ series-connected baths, we get the mass $km$ of rattlesnake gas. By burning this gas, we will get a lot of energy. For a sufficiently large $k$, this energy will exceed the original energy of the charged capacitor! Therefore, in some ways our reasoning is wrong. Find this error.
