Unformatted text preview: MEWORK 3 !!! ALL 1. E = 0 within the material of a conductor within Charges move inside a conductor in order to cancel out the fields that would be there in the absence of the conductor. This principle determines the induced charge densities on the surfaces of conductors. 2. Gauss’ Law: If charge distributions have sufficient symmetry (spherical, cylindrical, planar), then Gauss’ law can be used to determine the electric field everywhere. ∫ E idA = Q enclosed ε 0 ∆U a →b ≡ = − ∫ E ⋅ dl q a b 3.
