Document Summary
Basic idea that there is a finite amount of energy and it changes form. Work, force: energy physicists wanted to understand heat, force, work relationship. Electricity: wasn"t always clear that all electrical phenomena was the same thing, static electricity. First known type of electricity: reninous vs. vitreous electricity, friction machines. Able to generate large amount of static electricity. More of a novelty than a scientific instrument: leyden jar. Basically a simple capacitor: was thought of a fluid" of some kind. Frog legs twitched, people thought that it came from the animal and hence thought there was a type of animal electricity: voltaic pile. Gave experimenters a new source of steady, direct current: benjamin franklin. Wanted to demonstrate that all electric phenomena was the same. Aimed for the unity of electrical phenomena: ohm. Called it a force because of potential for motive work from charge in circuit.
