ELECTRICITY POWER EVOLUTION

 The evolution of electrical power has been a transformative journey, shaping modern civilization and driving technological progress. Here's an overview of its development through key stages:

---

1. Early Discoveries and Theoretical Foundations

• 600 BCE: Ancient Greeks observed static electricity by rubbing amber against cloth, coining the term "electric" from the Greek word "elektron."
• 1600 CE: William Gilbert published De Magnete, distinguishing between magnetism and electricity.
• 1752: Benjamin Franklin demonstrated that lightning is a form of electrical discharge using his famous kite experiment.

2. Development of Electrical Power Theories

• 1800: Alessandro Volta invented the first electric battery, the Voltaic Pile, providing a continuous source of electrical current.
• 1820s: Hans Christian Ørsted and André-Marie Ampère established the relationship between electricity and magnetism, leading to electromagnetism.
• 1831: Michael Faraday discovered electromagnetic induction, the principle behind electric generators and transformers.

3. Practical Applications and Invention of Devices

• 1879: Thomas Edison invented the practical incandescent light bulb, revolutionizing lighting.
• 1880s: Nikola Tesla developed alternating current (AC) systems, which could efficiently transmit electricity over long distances. Tesla and George Westinghouse advocated for AC, while Edison supported direct current (DC).
• 1886: The first commercial AC power station was built in Great Barrington, Massachusetts.
