Electrons and Ben Franklin

• Ben Franklin's "single fluid theory" showed that

• a given body possessing a normal amount of

• electric fluid was called neutral. During the

• process of charging, the fluid was transferred

• from one body to the other; the body with the

• deficiency being charged minus and the body

• with the excess charged plus . But no fluid is

• lost. Ben's "single fluid theory" led to the

• electron theory in 1900: electrons move about

• conductors much as a fluid might move.
