#6 Electric flux and Gauss' theorem | Class 11 NEB Physics | In Nepali
Physics in Depth・2 minutes read
Electric flux is determined by the component of the electric field vector that pierces a surface, with the unit of flux being newton meters. Gauss's theorem states that for a closed surface enclosing a charge, the electric flux is given by phi = k * q / epsilon naught, showcasing the relationship between electric flux and charge enclosed.
Insights
- Electric flux is determined by the component of the electric field vector that pierces a surface, with the formula del phi = e cos theta * del a, where theta is the angle between the electric field and the surface. The unit of flux is newton meters, and for a closed surface enclosing a charge, the electric flux is given by phi = k * q / epsilon naught, following Gauss's theorem.
- The proof of Gauss's theorem involves calculating the electric flux passing through a closed surface enclosing a charge, resulting in the final expression phi = q / epsilon naught, showcasing the relationship between electric flux and charge enclosed.
