The Discovery of Electricity

• Ancient Egyptians: believed electric fish were protectors of other fish

• Benjamin Franklin: proved lightning was electrical and stored electricity

• William Gilbert: distinguished between magnetism and static electricity

• Alessandro Volta: invented the first battery

• Michael Faraday: built an electric motor and generator

• Thomas Edison: invented the modern lightbulb

• Lewis Latimer: invented a filament for long-lasting lightbulbs

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.

The Discovery of Electricity

Key Discoveries:

• Alessandro Volta invented the first battery, known as the 'voltaic pile'.

• Michael Faraday built an electric motor and generator using Volta's discoveries.

• Thomas Edison improved the design of the lightbulb.

• Lewis Latimer invented the filament for long-lasting lightbulbs.

• War of the Currents: AC vs DC.

• Tesla's AC system and transformers led to the victory of AC current.

Lewis Latimer

Lewis Latimer invented the filament for long-lasting lightbulbs. His invention greatly improved the durability and efficiency of lightbulbs, making them more practical for everyday use. Latimer was a prominent African American inventor and engineer, and his contributions to the field of lighting technology were groundbreaking. Without his innovation, the modern lightbulb as we know it today may not exist.
