Ch. 22 Notes: Gauss's Law22.1: Charge and Electric Flux-Net
outward electric flux = positive enclosed charge-Net inward
electric flux = negative enclosed charge-Charges outside the
surface do NOT give a net electric flux through the surface-Net
electric flux is directly proportional to the net amount of charge
enclosed within the surface but is independent of size of the
closed surface22.2: Calculating Electric Flux-Electric flux for a
uniform electric field = phi_E = E*A = electric field
magnitude*Area-Electric flux for a nonuniform electric field =
phi_E = E_vector * dA_vector22.3: Gauss's Law-Electric flux through
a closed surface = q_enclosed/epsilon_naught22.4: Applications of
Gauss's Law22.5: Charges on Conductors-All excess charge goes on
outside of object. When a charged is placed inside a cavity,
charges will appear on the outside of the object and on the inside
of the cavity to balance out the new charge.-
