What's the difference between electricity and rheoscope?
Electricity
Definition:
(n.) A power in nature, a manifestation of energy, exhibiting itself when in disturbed equilibrium or in activity by a circuit movement, the fact of direction in which involves polarity, or opposition of properties in opposite directions; also, by attraction for many substances, by a law involving attraction between surfaces of unlike polarity, and repulsion between those of like; by exhibiting accumulated polar tension when the circuit is broken; and by producing heat, light, concussion, and often chemical changes when the circuit passes between the poles or through any imperfectly conducting substance or space. It is generally brought into action by any disturbance of molecular equilibrium, whether from a chemical, physical, or mechanical, cause.
(n.) The science which unfolds the phenomena and laws of electricity; electrical science.
(n.) Fig.: Electrifying energy or characteristic.
