Two identical capacitors Ca and Cb of capacitance 1.50 F areconnected in series across a total potential of 220 V. A dielectricslab of dielectric constant 6.55 can fill Ca and is slowly insertedinto that capacitor. (Note, account for any energy change by acorresponding energy change in some other part of thesystem.)
What is the change in charge, ?Qa, on Ca when the dielectric isadded to Ca?
What is the change in potential drop, ?Va, across Ca when thedielectric is added to Ca?
What is the change in total electric energy, ?U, of the twocapacitors when the dielectric is added to Ca?
