What You'll Learn
Thomas Edison's DC power
Thomas Edison is known for his contributions to the field of electricity, particularly his work on direct current (DC) power. Edison established the Edison Electric Illuminating Company in 1882, supplying electricity to a small area in New York City. This was a significant milestone in the history of electrical power, but it was not a nationwide solution.
Edison's DC system had limitations; it could only deliver electricity to customers within a mile of the plant, leaving many areas without electrical service. The system required heavy copper wires and was more expensive due to the rising price of copper. It also faced competition from alternating current (AC) systems, which could transmit power over longer distances from central generating stations.
Edison was involved in a battle with George Westinghouse over the adoption of DC or AC power, known as the "'War of Currents." Edison promoted the use of DC power and attempted to discredit AC power by showcasing its dangers, even staging events where animals were killed using Westinghouse's AC current. However, Westinghouse's AC system ultimately won out due to its ability to transmit power over longer distances.
Edison's DC system declined in the 20th century, with the last DC utility in New York City shutting down in 2007. However, the concept of using DC power for equipment located near the generator has seen a resurgence in data centers, where it can improve efficiency by reducing the number of power conversions required.
In addition to his work on DC power, Edison made significant contributions to technology, including the development of the first practical incandescent light bulb, the phonograph, silent movies, and improvements to the telephone.

George Westinghouse's AC power
George Westinghouse is credited with creating a delivery system for electricity through the promotion of alternating current (AC). Born on October 6, 1846, Westinghouse played a significant role in advancing the electrical distribution system in the United States during the late 19th century.
Westinghouse's adoption of alternating current allowed electricity to be transmitted over much greater distances than was possible with direct current (DC). This enabled power plants to supply electricity across large areas, including rural locations, and facilitated the establishment of electrical grids in cities and rural areas. The implementation of AC power enabled factories to operate around the clock with reliable electrical lighting, and towns were able to install electric streetlights, improving safety and mobility.
In 1886, Westinghouse founded the Westinghouse Electric Company, later renamed the Westinghouse Electric & Manufacturing Company, to focus on the development and commercialisation of AC power systems. He purchased the patents of Nikola Tesla's AC motor and hired Tesla to refine the motor for use in his power system. Westinghouse's company faced competition from Thomas Edison's direct current system, and a public relations battle ensued, known as the "War of Currents". Edison attempted to discredit AC power by showcasing its dangers, but ultimately, Westinghouse's AC system prevailed.
Westinghouse's innovations in AC technology culminated in the creation of the electrical grid, enabling the long-distance delivery of electricity. The Westinghouse Electric Company installed the world's first large-scale AC power generation plant at Niagara Falls, New York, in 1895. This development marked a significant advancement in the electrical industry and contributed greatly to industrial growth in America.

Electric lightbulb development
The development of the electric lightbulb was a milestone in human history, transforming the way we illuminate our nights and marking a significant advancement in the electric industry. The story of the lightbulb's invention began long before Thomas Edison patented the first commercially successful bulb in 1879.
In 1800, Italian inventor Alessandro Volta developed the first practical method of generating electricity with the voltaic pile, which is considered one of the earliest manifestations of incandescent lighting. Humphry Davy then produced the world's first electric lamp by connecting voltaic piles to charcoal. However, this lamp was not very practical as it burned out quickly and was too bright for everyday use. In 1840, British scientist Warren de la Rue created an efficient lightbulb using a coiled platinum filament, but it was not commercially successful due to the high cost of platinum.
In the 1850s, English chemist Joseph Swan began working on making electric lighting more economical. By 1860, he had developed a lightbulb with carbonized paper filaments, receiving a UK patent in 1878. Meanwhile, in 1874, Thomas Edison began working on a multiplex telegraphic system, which could send two messages simultaneously. In 1876, he established the first industrial research laboratory in Menlo Park, New Jersey, where he continued to innovate and experiment.
From 1878 to 1880, Edison and his associates tested over 3,000 designs for an efficient incandescent lamp. Finally, in January 1879, he created his first high-resistance, incandescent electric light. This design used a thin platinum filament in a glass vacuum bulb, delaying the filament from melting. However, the lamp only burned for a few hours. Edison then tested thousands of other materials for the filament, eventually settling on carbonized filaments, which required less electrical power to glow. In November 1879, he filed a patent for an electric lamp with a carbon filament.
Edison's work on the lightbulb and electrical distribution systems laid the foundation for further advancements. He established the Edison Electric Illuminating Company in 1882, supplying electricity to a small area in New York City. However, it was George Westinghouse's innovations in Alternating Current (AC) technology that enabled the long-distance delivery of electricity, leading to the establishment of the electrical grid.

The 'War of Currents'
The War of Currents was a battle between three brilliant inventors—Thomas Edison, Nikola Tesla, and George Westinghouse—over whose electricity system would become standard. Edison championed the direct-current (DC) system, while Tesla and Westinghouse promoted the alternating-current (AC) system.
Thomas Edison is often recognized for his numerous contributions to technology, including the incandescent light bulb, which he patented in 1879. Edison also established the Edison Electric Illuminating Company in 1882, which supplied electricity to a small area in New York City. This was a milestone in providing electrical power, but it was not a nationwide solution. Edison's DC plants could not deliver electricity to customers more than one mile from the plant, and the high voltages used in AC systems were seen as dangerous.
George Westinghouse, on the other hand, founded the Westinghouse Electric Company in 1886 and focused on the development and commercialization of AC power systems. AC power allowed electricity to be transmitted over long distances, revolutionizing how electricity was delivered and accessed. Westinghouse's AC system used transformers to step down from a high voltage so that AC could be used for indoor lighting.
The War of Currents grew out of the development of two lighting systems: arc lighting running on AC and incandescent lighting running on DC. Both were supplanting gas lighting systems, with arc lighting taking over street lighting and large areas, and incandescent lighting replacing gas for business and residential indoor lighting.
During the War of Currents, Edison launched a propaganda campaign to discredit AC, claiming it was dangerous. Animals were publicly electrocuted with AC, and when New York State sought a more humane alternative to hanging for death-row prisoners, Edison recommended AC-powered electrocution. In 1890, convicted murderer William Kemmler became the first person to die in the electric chair, powered by a Westinghouse AC generator. Despite Edison's efforts, Westinghouse won the contract to supply electricity to the 1893 World's Fair in Chicago, beating Edison's company, which had merged with its chief AC rival to form General Electric in 1892.
The War of Currents ended with AC becoming dominant in the electric power industry. In 1896, Westinghouse's AC system started delivering electricity to Buffalo, New York, 26 miles away. Today, electricity is still predominantly powered by AC, but DC is used in computers, LEDs, solar cells, and electric vehicles.
