1

Electric flux

  • product of area ⊥ field lines and electric field

    • The “amount” of electric field passing through a given surface

2

Gauss’s Law

  • Net flux is dependent only on charge inside the gaussian surface

3

gaussian surface

a closed surface which, by definition, follows Gauss’s Law & whose e-flux can be found

4

electrostatic equilibrium

Net charge motion is zero

  • ∑Fe = 0

5

conductor in ES equilibrium

  1. E = 0 inside surface (including cavities)

  2. Charge (if there is one) accumulates on the surface

  3. E = σ/ε0 just outside surface

  4. Smallest radius of curvature = greatest charge

    • for irregularly-shaped surfaces
