Electric Field

The video tutorial explains the concept of electric fields, which are physical quantities that exert forces on charges. It covers the nature of electric fields produced by positive and negative charges, and how field strength decreases with distance. The tutorial also delves into the mathematical calculations of electric fields, including spherical symmetry and the superposition principle for systems of charges. Finally, it highlights the practical applications of electric fields in technology, such as in cathode ray tubes and accelerators.
