Charge on an electron by Millikan's method | 12th class physics |Millikan's oil drop experiment

In this video I have discussed the basic concepts of the charge on an electron by Millikan's method also called Millikan's oil drop experiment. The queries solved in this video are 1. How Millikan find charge on an electron? 2. Why we use oil in Millikan oil drop experiment instead of water? 3.How we find the radius of droplet? 4. How we find the mass of charge droplets? 5. How droplet gets negatively charged? 6. What is the function of atomizer? 7. Why we use X-ray source? 8. How charge droplets suspend in air? 9. What type of forces act on charge droplets when voltage source is off? 10. What type of forces acts on charge droplets when voltage source is ON? 11. Construction of Millikan's oil drop experiment. 12. Calculation by Millikan's to find the charge on an electron. 13. Results calculated by Millikan by his experiment. 14. What is meant by integral multiple of minimum charge? 15. Working of Millikan's oil drop experiment. follow my TikTok account https://vt.tiktok.com/ZSdPyYqwv/ follow my Instagram account https://instagram.com/physicskasafar?... follow my Facebook page https://www.facebook.com/groups/56944...
