Physics 1260 Exam Study Guide |UPDATED| #Latest Release Two types of charges exist *Ans* Positive and negative Like charges *Ans* repel unlike charges *Ans* attract each other Electrons can *Ans* freely move in conductors, but not in insulators (dielectrics) Conduction *Ans* electric charges move freely in response to an electric force Induction *Ans* materials in which electric charges do NOT move freely b/c all electrons are tightly bound to the nucleus (up to a certain extent) The Superposition Principle *Ans* The resultant (total) force on any one charge equals the vector sum of the forces exerted by all the other individual charges that are present. The direction of the E-field is *Ans* the direction of the electric force that would be exerted on a small positive test charge placed at that point E-field lines point *Ans* Away from positive charges and toward negative charges From high potential (V) to low potential E-Field: Flux *Ans* Gaussian surface "catches" E-field lines (like a wind-sock) Open surface (like a net), use: *Ans*
