Two identical capacitors (A and B) with capacitance Co are hooked up to a battery of voltage Vo. A dielectric of constant Ko is added between the plates of capacitor B while it is connected to the battery, as in the figure at right. Is the charge on capacitor A (QA) greater than, less than, or equal to the charge on capacitor B (QB)? What about the voltages (VA and VB)? Explain your reasoning. CB The capacitors above are carefully disconnected from the battery (without being discharged), after the battery is disconnected the dielectric slab is removed from capacitor B. The capacitors remain connected to each other the entire time. b) Determine an expression for the final charges on each of the capacitors (QA,ƒ and QB,f) after the dielectric has been removed in terms of the given constants (Ko, Co, Vo). Show your work and explain your reasoning.
