Electroplating
The electroplating process was first discovered by Italian chemist Luigi Brugnatelli in 1805. However, his discovery was not recognized by the French Academy of Science or Napoleon Bonaparte, who ordered that his work be kept secret. As a result, the science of electroplating was reinvented in England a couple of decades later, and John Wright managed to use potassium cyanide as an electrolyte for gold and silver. In 1840, the Elkington cousins used potassium cyanide as their electrolyte and created a feasible electroplating method for gold and silver, which became widespread throughout the world.
The electroplating process was significantly boosted by the development of electric generators in the late 19th century, which provided higher currents that allowed for the bulk processing of metal machine components, hardware, and automotive parts. The two World Wars and the growing aviation industry further propelled advancements in electroplating, leading to the development of various plating processes such as hard chromium plating, bronze alloy plating, and sulfamate nickel plating.
If electricity had been discovered sooner, it is possible that electroplating could have been developed earlier, potentially accelerating the progress of industries that heavily rely on this technique, such as electronics, automobiles, airplanes, jewelry, and toys. However, as discussed in the context of early electricity discovery, there were other limiting factors at play, including the lack of necessary materials, mathematical understanding, and economic and social structures to support widespread technological advancements.
Therefore, while an earlier discovery of electricity may have provided an opportunity for the earlier development of electroplating, it is challenging to predict the exact timeline and impact on various industries without a more comprehensive understanding of the complex interplay between scientific knowledge, available resources, and societal factors.

Alternating-current electrical system
The "War of Currents" in the late 19th century saw Thomas Edison and George Westinghouse battle it out over direct current (DC) and alternating current (AC) electricity systems. Edison, who had invented a meter to allow customers to be billed for energy proportional to consumption, was a proponent of DC. However, DC had a short transmission range and was not easily convertible to higher or lower voltages.
The fundamental principles of AC electricity were discovered by Michael Faraday in 1831, who demonstrated that a changing magnetic field could induce an electric current, a phenomenon known as electromagnetic induction. This led to the invention of the electric generator, which creates power by spinning a magnet near a coil of wire.
In the 1880s, Nikola Tesla and Westinghouse further developed AC systems, recognising their advantages for long-distance power distribution. Tesla designed the first efficient AC motors and transformers, making widespread AC transmission possible. AC can be converted to different voltages relatively easily using a transformer, and AC systems can raise voltage levels, allowing electricity to be transmitted over long distances with minimal energy loss.
In 1886, Westinghouse and William Stanley installed the first multiple-voltage AC power system, a demonstration incandescent lighting system in Great Barrington, Massachusetts. By the end of 1887, Westinghouse had 68 alternating current power stations across the US. In 1891, the first three-phase system was established in Frankfurt, Germany, and in 1893, Westinghouse built an alternating current system for the Chicago World's Fair, lighting up the city of Buffalo, New York.
The adoption of AC over DC during the "War of Currents" was due to the efforts of pioneers like Tesla and Westinghouse, who recognised the potential of AC for efficient long-distance power distribution.
