Hey Buddy! Let's dive deep into the electrifying world of Physics and unravel the mysteries of charges. 🌩️

Did you know? 🎈

🔹 Static Shock: Ever rubbed your feet on a carpet and got a little shock touching a doorknob? That’s static electricity! Similarly, you can use a plastic comb, run it through your hair, and watch it magically pick up pieces of paper! It's like giving superpowers to the comb! 🦸‍♂️

 

🔹 Ancient Electromania: The ancient Greeks discovered this cool trick 2600 years ago. They noticed that when they spun silk on amber, the silk got attracted to the amber. They called amber "ηλεκτρον" (electron). And guess what? That's where we get our modern term "electron" from! 🏺

Charges & their discovery ⚡

Two Types, Not One!: In the 1700s, a guy named du Fay realized that it wasn't just a one-type-show. Both materials could get "electrified", and there were two opposite kinds. So, it’s like the superhero and the supervillain in comics – positive and negative!

 

🔹 Benjamin Franklin & His Brave Kites: Benjamin Franklin, besides being on the $100 bill, did some wild experiments! 🎏 Imagine flying a kite during a storm! 🌩️ Crazy right? But that's how he explored charges. He called the charge on a glass rod rubbed with silk as “positive electricity” and the other one “negative”.

Dive into the atom 🧪

🔹 J.J. Thomson's Discovery: Fast forward to the 19th century. J.J. Thomson found a teeny-tiny particle - the electron. It’s like finding Waldo, but in the world of atoms!

 

🔹 Electron's Family: So, atoms have these electrons, but wait, there’s more! They also have protons. And here’s the twist - while electrons have a negative charge, protons have the opposite: a positive charge. And these are the only two types of charges we know!

 

🔹 Changing Perspectives: Unlike what our buddy Franklin thought, today we say electron = negative, proton = positive.
