  1. If the areas are A1 and A-A1. C123 2.4 µF, q = 28.8 µC C2C24 = 12 µF C1234 = 3 µF q =36 µC

  2. The force on a filling dielectric as it is inserted between the parallel plates of a capacitor. x L With the battery connected, U1 = ½CV2 With the battery disconnected, U2 = Q2/2C With the battery connected, since x is increasing downwards, a negative force is upwards, pushing the dielectric away. With the battery disconnected, the force is positive and pointed downwards, pulling in the dielectric. The force is proportional to (κ-1) and inversely to L.

  3. Chapter 26 Current and Resistance In this chapter we will introduce the following new concepts: -Electric current ( symbol i ) -Electric current density vector (symbol ) -Drift speed (symbol vd) -Resistance (symbol R ) and resistivity (symbol ρ ) of a conductor -Ohmic and non-Ohmic conductors We will also cover the following topics: -Ohm’s law -Power in electric circuits (26 - 1)

  4. HITT The plate areas and plate separations of five parallel plate capacitors are capacitor 1: area A0, separation d0 capacitor 2: area 2A0, separation 2d0 capacitor 3: area 2A0, separation d0/2 capacitor 4: area A0/2, separation 2d0 capacitor 5: area A0, separation d0/2 Rank these according to their capacitances, least to greatest. a. 1,2,3,4,5 b. 5,4,3,2,1 c.
