summary
Gauss’ Law: Electric field flux out of a closed surface is proportional to the net charge enclosed
- Gauss’ Law is exact and always true….
- Gauss’ Law makes solving for E-field easy when the symmetry is sufficient
- spherical, cylindrical, planar
- Gauss’ Law proves that electric fields vanish in conductor
- extra charges reside on surface
Next time: Electric potential and potential energy
