While electricity was certainly known about in the 1840s, with important discoveries being made in the field, it was not yet available in homes. In fact, it wasn't until about 1890 that electricity began to be installed in homes, and even then, it was a luxury item. The first American home to be powered by hydroelectricity was in 1882, and by 1945, 85% of American homes were powered by electricity.

What You'll Learn
The first electric battery was invented in 1800
The existence of electricity in homes in the 1840s is hard to pinpoint. However, it is known that in the early days of electrification, electricity was transmitted through bare copper wires with minimal cotton insulation. Sockets, switch handles, and fuse blocks were made of wood, and there were no voltage regulators, which resulted in lights dimming and brightening according to the demand on the electrical grid.
The first electric battery was invented by Alessandro Volta in 1799, and he communicated his invention to the Royal Society of London in 1800. This battery, known as the Voltaic Pile, had some technical flaws, including electrolyte leakage and a short battery life of about an hour. However, it provided a steadier current than Leyden jars and enabled new experiments, such as the first electrolysis of water.
Volta's studies were inspired by the work of Luigi Galvani, who investigated the existence of intrinsic electricity in living organisms, known as "animal electricity." Volta's work built upon this knowledge and marked the beginning of modern neuroscience.
The Voltaic Pile consisted of a series of results that were physiologically significant. However, Volta's cultural legacy has often been solely associated with physics, neglecting his contributions to biology and neuroscience.
Over time, improvements were made to the original design of the electric battery. For example, William Cruickshank, a Scotsman, addressed the issue of electrolyte leakage by rearranging the elements horizontally in a box instead of piling them, creating what became known as the trough battery. Volta also invented a variation called the Crown of Cups, which consisted of a chain of cups filled with a salt solution linked by metallic arcs.
The development of the electric battery played a crucial role in the advancement of electricity, paving the way for early scientific studies, the emergence of telegraphs and telephones, and eventually leading to portable computers, mobile phones, and electric cars, among other electrical innovations.

The first telegraph line was constructed in the 1840s
In the 1840s, the world witnessed a significant leap forward in the form of the first telegraph line. This groundbreaking innovation revolutionised communication, allowing instant messaging over vast distances for the first time in human history. The printing press, which had been the primary mode of mass communication, was now complemented by this new marvel.
The electrical telegraph, or telegraphy, as it was called, was the first electrical telecommunications system. It involved sending electric signals over wires between two or more geographically separated stations, known as telegraph offices. This technology superseded optical telegraph systems, such as semaphores, and became the standard way to send urgent messages quickly across long distances.
The story of the telegraph began even earlier, with English inventor Francis Ronalds building the first working telegraph in 1816. Ronalds set up a complete subterranean system in a 175-yard-long trench and an eight-mile-long overhead telegraph at his family home. However, his invention was rejected by the Admiralty as "wholly unnecessary". Despite this setback, Ronalds' work laid the foundation for the future commercialisation of the telegraph.
In the 1830s, several pioneers made significant contributions to the development of the telegraph. Carl Friedrich Gauss, for instance, installed a 1,200-metre-long wire above the roofs of Göttingen, Germany. He combined the Poggendorff-Schweigger multiplicator with his magnetometer to create a more sensitive device, the galvanometer. This allowed him to change the direction of the electric current and move a distant needle into the desired position.
By the end of the 1840s, the impact of the telegraph was being felt across the eastern states of the US, with telegraph lines connecting towns and cities. In 1844, Samuel Morse sent the first message on a 40-mile telegraph line from the US Capitol Building to Baltimore's Mt. Claire Station, marking a pivotal moment in the history of communication. The message, "What hath God wrought?", highlighted the transformative power of this new technology.
While the 1840s saw the construction of the first telegraph lines, the electrification of homes was still in its infancy. It wasn't until the late 19th century and early 20th century that electricity began to be used in homes, initially for lighting, and then gradually for a range of appliances as the decades progressed.

The first home powered by hydroelectricity was in 1882
While the concept of electricity was known before 1840, it was not common in homes at that time. The use of electricity in homes became more prevalent later in the 19th century, with significant developments in the 1880s.
In 1882, the world's first hydroelectric power station, the Vulcan Street Plant, began operating in Appleton, Wisconsin. This development marked a significant milestone in the history of electricity and paved the way for its wider adoption. The brain behind this project was businessman H.J. Rogers, who, inspired by Edison's planned steam-powered station in New York, recognised the potential of harnessing the nearby Fox River for generating electricity.
Rogers, along with A.L. Smith, H.D. Smith, and Charles Beveridge, founded the Appleton Edison Light Company. Despite initial setbacks, including lamp failures during the opening ceremony, the company persevered. They successfully provided electricity to two additional homes near Vulcan Street in November 1882, and by the end of that year, several more homes, mills, and even a blast furnace were lit up by electric bulbs.
The success of the Vulcan Street Plant and other early power stations highlighted the limitations of Thomas Edison's direct current systems, which were unsuitable for long-distance electricity transmission. This challenge was eventually overcome by Nikola Tesla and George Westinghouse, who pioneered the use of alternating current, enabling the transmission of power over longer distances. This breakthrough led to the first U.S. commercial installation of an alternating current hydropower plant at the Redlands Power Plant in California in 1893.

The first incandescent lamp patent was in the 1840s
In the 1840s, electricity was a novelty, with its primary use being lighting. In 1840, English scientist William Robert Grove created the first electric light, lighting an auditorium with incandescent lamps. These lamps were made of platinum coils encased in an inverted glass sealed by water. However, they were too expensive and impractical for commercial use.
In 1841, Frederik de Moleyns received the first patent for an incandescent lamp. His design involved mounting a powdered charcoal filament between two platinum wires in a glass bulb under a vacuum. In 1845, Thomas Wright of London produced the first arc lamp, which had automatically regulated carbons in the form of disks that were rotated by clockwork. This was followed by the development of various regulating mechanisms by investigators in Europe and America.
In 1846, John Doper patented a platinum filament incandescent electric lamp. Platinum's high melting point allowed the filament to operate at a higher temperature than other tested metallic elements. However, the high cost and scarcity of platinum made this design impractical for widespread use.
In the late 1870s, Thomas Edison and Joseph Wilson Swan independently produced carbon filament incandescent lamps that burned for a practical length of time. Edison's first bulbs lasted 13.5 hours, and later improvements extended this to 40 hours. Swan's bulbs, which used carbonized paper as a filament, lasted several hours, a remarkable achievement compared to other inventors' attempts.
On January 27, 1880, Thomas Edison received a patent for his improvements to electric lamps, using a carbon filament. This design was reliable, safe, and practical, paving the way for the universal domestic use of electric light.

Electricity was a luxury item 125 years ago
The history of electricity is a fascinating one, with experiments and innovations dating back to the 1700s. English scientist Francis Hauksbee, for example, made a glass ball in the early 1700s that glowed when rubbed, demonstrating electrical attraction and repulsion. This discovery would eventually lead to neon lighting. In the 1840s, the first electric telegraph lines were constructed, and inventors like Frederick de Moleyns were granted patents for early incandescent lamps. Despite these advancements, electricity was still largely a work in progress and not yet a staple of daily life.
It wasn't until the late 19th and early 20th centuries that electricity began to be adopted more widely. In 1882, a house in Appleton, Wisconsin became the first American home to be powered by hydroelectricity, using Thomas Edison's direct current (DC) system. This marked the beginning of the American power system, which has since grown into an extensive network of interconnected grids and power lines. By the 1940s and 1950s, electricity was primarily used for lighting in American homes, and the introduction of new appliances, such as vacuum cleaners, refrigerators, and washing machines, drove up demand for more power.
Today, electricity is an indispensable part of modern life. The American electrical system, for instance, comprises nearly 450,000 miles of power lines and 160,000 miles of overhead transmission lines, supplying almost 4 trillion kilowatt-hours of power annually. This vast infrastructure is supported by thousands of power linemen and companies, ensuring a consistent supply of electricity to power the myriad appliances and electronic devices we rely on daily.
Looking to the future, the demand for electricity is only expected to grow as our homes and appliances become "smarter". There is also a growing focus on transitioning to renewable power sources, such as wind, solar, and hydroelectric power, and improving energy efficiency.
