1. E = 0 within the material of a conductor
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
b 3. Definition of Potential: ∆Va →b CONCEPTS DETERMINE THE CALCULATION !!!
