The word electricity comes from New Latin e-lectricus, meaning like amber. Electricity is all about the presence and flow of an electric charge. We see it in nature, in lightning. We see it in every day life when someone rubs a wool garment and gets a spark of static electricity. More scientific aspects of this flow of an electric charge are seen in an electromagnetic field and electromagnetic induction.
In everyday life, the word electricity is understood, but in the world of the scientist, it's considered too vague so more exact and definitive words are preferred. Some of these precise terms used in the lab are: Electric Potential, Electric Current, Electromagnetism, etc.
History
Man has studied electrical phenomena since ancient days. Finally, in the 17th and 18th centuries, the mysteries began to be solved. Still, little practical applications for this phenomena existed until late in the 19th century when engineers began to use it in homes and industries.
Thus, the Industrial Age blossomed. Society and industry alike changed, and the change continues today with new applications continuing unabated.
Bringing Meaning to Madness
Electricity is one of the foundations of modern society. Our infrastructure is built upon it. If you think that's overstating the case, just try existing when the power goes out for days as it sometimes does here in hurricane country.
