The late 1880s marked a pivotal moment in the history of electricity, characterized by the fierce rivalry between two visionaries: George Westinghouse and Thomas Edison. This contest, famously termed the 'War of Currents,' proved to be the defining battle that determined the prevailing standard for electricity generation in modern times. The clash centered on the promotion of two distinct forms of electric current—Edison championing direct current (DC) and Westinghouse, alongside Nikola Tesla, advocating for alternating current (AC).
At the outset, Thomas Edison's direct current system gained prominence as the primary method for electricity distribution across the United States.
DC showcased compatibility with incandescent lamps, the predominant load during that era. Moreover, its seamless integration with storage batteries provided crucial load-levelling capabilities and backup power during generator downtimes. Edison's innovation extended to the invention of a meter for billing customers based on energy consumption, albeit compatible only with DC.
However, the limitations of DC soon emerged prominently.

A significant drawback lay in its inability to be efficiently transmitted over long distances due to the necessity of using hefty currents in conductors. Consequently, this led to exorbitant energy losses beyond distances of a few kilometers, demanding numerous power stations and an extensive network of wires to cater to the electricity needs of larger urban areas.
On the other front, George Westinghouse and Nikola Tesla pioneered the AC generators, effectively addressing the deficiencies of DC. The transformative use of transformers enabled the modulation of voltage, allowing for the generation of AC at lower voltages, subsequent amplification for long-distance transmission, and reduction to lower voltages at consumer endpoints.
This breakthrough in voltage regulation not only facilitated the transmission of AC over vast distances but also significantly mitigated energy losses.
The innovation of the induction motor by Tesla further bolstered the ascendancy of AC. This motor, exclusively operational on AC, contributed substantially to the surge in AC's popularity. Furthermore, AC generators proved to be more cost-effective, simpler to assemble, and required less maintenance than their DC counterparts due to the absence of a commutator.
As AC supplanted DC in power generation and distribution, it revolutionized the safety, efficiency, and reach of electricity supply networks, much to Edison's chagrin. Despite Edison's relentless efforts to thwart AC's adoption, employing tactics such as highlighting fatal accidents involving AC, public demonstrations of animal electrocution, and lobbying against AC in legislative arenas, the superiority of AC prevailed.
Nonetheless, certain applications continued to necessitate the use of DC, particularly in metal purification and chlorine production. These specialized domains underscored the enduring relevance and utility of direct current, preserving its significance despite the overwhelming triumph of AC in mainstream power supply.
In conclusion, the 'War of Currents' between Edison's DC and Westinghouse-Tesla's AC stands as a testament to the transformative power of innovation and technological competition in shaping the course of history. The victory of alternating current revolutionized the landscape of electricity generation and distribution, ushering in an era of enhanced efficiency, safety, and wider accessibility to electric power. While Edison's direct current faced defeat in becoming the predominant method of electricity supply, its specialized applications continue to endure, highlighting the diverse and nuanced roles different currents play in the modern technological landscape.
Ultimately, this clash between two brilliant minds left an indelible mark on the world, emphasizing the enduring impact of their contributions in shaping the foundation of contemporary electrical systems.
