Start Of The Electrical Age
On September 4, 1882, Thomas Edison began providing electricity to a portion of New York City, an event often considered the start of the electrical age.
Electric arc lighting had existed since the early 1800s, but the frequent need to replace carbon tips and bright light meant these were best used outside or in very large rooms. Throughout the 1800s, inventors experimented with incandescent electric lighting for use indoors.
