ELECTRIC FLUX AND GAUSS'S LAW!
Electric Field Flux
Φ
E
= ΔA E cosθ
For the examples we do, we will depend heavily on SYMMETRY!
For a spherical distribution, we use a spherical Gaussian surface...
"Infinite" sheet of charge.
Use a Gaussian "pillbox!"
Your hair can be used to trace out electric field lines.
