Coulomb's Law and Electric Field Intensity Explained (with Solved Example) | Electromagnetic Theory

In this video, Coulomb’s Law and the concept of electric field are explained with a solved example for better understanding. In the later part of the video, real-world applications—such as laser printers and electrostatic precipitators—are illustrated to show how electrostatic charges and the forces between them play a crucial role.

Electrostatics is the branch of electromagnetics that deals with electric charges at rest and the forces, fields, and potentials associated with them. Coulomb's Law The electrostatic Force between the two point charges Q1 and Q2 is directly proportional to the product of the Q1 and Q2 and it is inversely proportional to the square of the distance R between them. Mathematically, the electrostatic force F between two charges can be given as F = k Q1Q2 / R² Unit - Newton (N) Electric Field Intensity Electric field intensity at a given point is defined as the force experienced per unit positive test charge placed at that point. E = F / Qt, where, Qt is a test charge Unit - N / C or V/m For more videos on Electromagnetic Field Theory, check this playlist: https://bit.ly/4nrqFDv For more video on Analog Electronics, check this playlist https://bit.ly/3QtqdnN For more video on Digital Electronics, check this playlist https://bit.ly/31gBwMa This video will be helpful to all the students of science and engineering in understanding the Coulomb's Law and the concept of Electric Field Intensity. #allaboutelectronics #coulombslaw #electricfieldintensity #emft Support the channel through membership program:    / @allaboutelectronics   -------------------------------------------------------------------------------------------------- Follow my second channel:    / @allaboutelectronics-quiz   Follow me on WhatsApp channel: https://www.whatsapp.com/channel/0029...
