Electric Chair Question? (Green Mile movie spoiler)

When Eduard Delacroix (the bald little guy with the pet mouse) gets executed and Percy doesn’t use the wet sponge on his head, could it possible have been that bad/taken that long?

Please no debates about death penalty, cruel punishment, etc. Just someone with a working knowledge of electricity let me know if that scene was at all accurate.

…But I would say yes. See this link:

It seems to take an anti-death penalty stance, but it also seems to provide some pretty in-depth detail, and eyewitness accounts (of course, this IS the internet we’re talking about. It’s possible this never happened, and none of the eyewitnesses existed. But I digress). The links at the top of the page didn’t work for me, so you may have to scroll down to read the details. Hope this helps!
