The Discovery of Electricity

• AC vs DC: There was a real war about whether AC or DC would be used to power homes and buildings.

• AC Advantages: AC can be easily transformed and transferred at high voltages, making it more efficient and safer.

• DC Disadvantages: DC cannot be easily transformed and needs to be closer to buildings.

• Edison vs Tesla: Edison preferred DC while Tesla invented a more efficient AC system.

• AC's Victory: Tesla's invention of transformers led to the victory of AC current.

Tesla and the AC Revolution

Nikola Tesla invented a more efficient AC (alternating current) system, which revolutionized the way electricity is transmitted and distributed. His AC system allowed for long-distance power transmission, making it possible to power entire cities from a central power plant. This innovation paved the way for the modern electrical grid and is still widely used today.
