The "Age of Electric" refers to the period in history marked by the widespread adoption of electric power and technology. This era began in the late 19th century and transformed industries, homes, and daily life. Innovations such as the electric light bulb, developed by Thomas Edison, and the electric motor revolutionized how people lived and worked. During this time, cities expanded rapidly as electric infrastructure was built, leading to the growth of public transportation systems like trams and subways. The Age of Electric also paved the way for modern conveniences, including household appliances and communication devices, fundamentally changing society's dynamics and economic structures.
