Franklin's theory stated that electricity should be thought of as the movement of a single liquid, as opposed to the interaction between two liquids. A body would show signs of electricity when it held either too much, or too little of this liquid. A neutral object was therefore thought to contain a “normal” amount of this fluid.
The term "electric fluid" was sometimes used to describe electrical forces which are generated by what science now refers to as an electric field. For example, a basic electric pendulum consists of weights to which an electric charge has been applied, such as through the static electric effect. As masses with similar charges (i.e. both positive ...
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations.
Liquid crystal: Properties intermediate between liquids and crystals. Generally, able to flow like a liquid but exhibiting long-range orientational order. Supercritical fluid: A fluid with properties intermediate of liquids and gasses. At sufficiently high temperatures and pressures, the distinction between liquid and gas disappears, resulting ...
The ER fluid changes from a Newtonian liquid to a partially crystalline "semi-hard slush". However, an almost complete liquid to solid phase change can be obtained when the electrorheological fluid additionally experiences compressive stress. [15] This effect has been used to provide electrorheological Braille displays [16] and very effective ...
In a string-net liquid, atoms have apparently unstable arrangement, like a liquid, but are still consistent in overall pattern, like a solid. When in a normal solid state, the atoms of matter align themselves in a grid pattern, so that the spin of any electron is the opposite of the spin of all electrons touching it.
Du Fay announced that electricity consisted of two fluids: "vitreous" (from the Latin for "glass"), or positive, electricity; and "resinous," or negative, electricity. This was the two-fluid theory of electricity, which was to be opposed by Benjamin Franklin's one-fluid theory later in the century. [4]
