3. Electricity Electricity is a fundamental form of energy characterized by the flow of charged particles, typically electrons, through conductive materials. It encompasses various phenomena related to the interaction of charged particles and electromagnetic fields, including the generation, transmission, and utilization of electrical energy for powering devices, producing light, heat, and performing mechanical work.

4. Ancient Discoveries Early Scientific Studies Development of Theories Modern Era Advancements in Power Distribution Invention of Electric Generators and Motors

5. Ancient Discoveries The invention of the electric generator by Michael Faraday and others in the early 19th century enabled the conversion of mechanical energy into electrical energy. This led to the development of electric motors by inventors like Thomas Davenport and Nikola Tesla, which allowed for the conversion of electrical energy back into mechanical energy.

6. Early Scientific Studies In the 17th and 18th centuries, scientists like William Gilbert, Otto von Guericke, and Benjamin Franklin conducted experiments and made significant contributions to understanding electricity. Gilbert coined the term "electricity" from the Greek word for amber. Franklin famously conducted his kite experiment in 1752, demonstrating the connection between lightning and electricity.

7. Development of Theories In the 19th century, scientists like Michael Faraday and James Clerk Maxwell developed theories that laid the foundation for modern electromagnetism. Faraday's work on electromagnetic induction in the early 1800s paved the way for the practical use of electricity in generating electric power. Maxwell's equations, formulated in the mid-19th century, provided a unified theory of electromagnetism.

8. Invention of Electric Generators and Motors The invention of the electric generator by Michael Faraday and others in the early 19th century enabled the conversion of mechanical energy into electrical energy. This led to the development of electric motors by inventors like Thomas Davenport and Nikola Tesla, which allowed for the conversion of electrical energy back into mechanical energy.

9. Advancements in Power Distribution In the late 19th and early 20th centuries, inventors like Thomas Edison and George Westinghouse played significant roles in developing systems for generating and distributing electrical power.. Edison's development of the first commercial electric power station in 1882 and Westinghouse's promotion of alternating current (AC) systems helped to establish electricity as a practical energy source for homes and industry.

10. Modern Era In the 20th and 21st centuries, electricity became an essential part of daily life, powering homes, businesses, transportation, communication, and industry. Advances in technology, such as semiconductor devices, computer systems, and renewable energy technologies, have continued to shape the way electricity is generated, distributed, and used.

11. Maxwell

12. Who Was Maxwell? James Clerk Maxwell , was a brilliant scientist from Scotland who lived in the 19th century. He's famous for his work in physics, especially for something called "Maxwell's equations." Maxwell was like a detective but for science. He loved to solve puzzles about how things work in the world.

13. A Curious Mind Maxwell was born in Scotland in 1831. Even as a child, he loved to ask questions and figure out how things worked. He He was really good at math and science, and he used his skills to explore the mysteries of the universe.

14. Unraveling the Mysteries of Electricity and Magnetism One of Maxwell's biggest discoveries was figuring out how electricity and magnetism are connected. He realized that electric and magnetic fields are linked and that they can change each other in really cool ways.

15. Maxwell's Equations Maxwell wrote down a set of equations, called Maxwell's equations, that describe how electric and magnetic fields interact. These equations are like a secret code that scientists use to understand how electricity and magnetism work together.

16. Legacy Maxwell's work laid the foundation for modern physics and technology. His equations helped pave the way for things like electric power, radio, and even the internet! Today, scientists still use Maxwell's equations to explore the mysteries of the universe and make new discoveries.

18. Gauss’s Law for Electricity This equation relates the electric field (𝐸) to the electric charge density ( ρ ) . 01 02 It states that the electric flux through a closed surface is proportional to the total electric charge enclosed by the surface. 03 Mathematically , it's written as: -- Permittivity : Physical Constants

19. Gauss’s Law for Magnetism This equation states that the magnetic flux through a closed surface is always zero. 01 02 It implies that there are no magnetic monopoles (isolated magnetic charges). 03 Mathematically , it's written as:

20. Faraday's Law of Electromagnetic Induction This equation describes how a changing magnetic field produces an electric field and induces electromotive force (EMF) in a closed loop. 01 02 It relates the induced electric field (𝐸) to the rate of change of the magnetic flux (∂𝐵/∂𝑡​). 03 Mathematically , it's written as:

21. Ampère's Law with Maxwell's Addition This equation relates the magnetic field (𝐵) to the electric current density (𝐽) and the rate of change of the electric field. 01 02 Maxwell added the displacement current term (𝜀0 ∂𝐸/∂𝑡​) to Ampère's Law to account for changing electric fields producing magnetic fields . 03 Mathematically , it's written as: -- permeability : Physical Constants
