Science:Humphry Davy Inventor of the First Electric Light Connection Post

I think this can relate to Frankenstein because obviously people needed a way to light there houses or light there way while in a dark area. Also when the people went after the creature or when Frankenstein was looking for body parts he could have been using Humphry Davys Electric Light.

Science:Humphry Davy Inventor of the First Electric Light.

 Humphry Davy invented the first electric light in 1809. He created this light by connecting two wires to a battery. Then he connected a charcoal strip between the other ends of the wires. The carbon would glow from this thus creating the first electric (arch) lamp.

How the Voltaic Pile Relates to Frankenstein

I feel since the Voltaic Pile was a source of electricity it related to Frankenstein because one of the key elements to bringing the creature to life was electricity. Although the source that brought the creature to life was lighting the machines that Frankenstein had used electricity possibly running on a Voltaic Pile.

Alessandro Volta And The Invention of the Voltaic Pile

In 1800 a man by the name of Alessandro Volta  invented  the "Voltaic pile".  He also invented the first practical way to generate electricity. Volta also made many inventions in the fields of electrostatics, meteorology and pneumatics.  The voltaic pile consisted of alternating disks that were made of zinc and copper and had cardboard soaked in brine between the metals.  The pile created an electrical current and it was a steady electrical current.
