Etymology: < electric adj. + -ity suffix; compare -icity suffix.
I. Literal senses.
1.
a. In early use: the property of amber, glass, and certain other substances of attracting lightweight objects when rubbed (cf. electric adj. 1a); (also) the state produced in such substances by rubbing. Subsequently: the cause of this phenomenon (and of others found to be of the same origin, such as electric sparks and lightning), a form of energy occurring in two modes (positive and negative) as an intrinsic property of electrons and certain other subatomic particles, and produced as a flowing current when a conductor such as a copper wire is moved through a magnetic field.Benjamin Franklin considered electric phenomena to be due to a fluid (see electric fluid n.). Later in the 19th cent. the prevailing view was that electricity is a distinctive condition either of the molecules of an electrified object or of the ether surrounding it.
