Homework Statement
Two identical capacitors Ca and Cb each of capacitance 6.60 http://lon-capa.mines.edu/adm/jsMath/fonts/cmmi10/alpha/100/char16.png F are connected in parallel across a CONSTANT total electric potential difference of 480 V. A dielectric slab of dielectric constant 4.65 can fill Ca and is slowly inserted into that capacitor.
What is the change in charge, [PLAIN]http://lon-capa.mines.edu/adm/jsMath/fonts/cmr10/alpha/100/char01.pngQa, on Ca when the dielectric is added to Ca?
Homework Equations
C=Q/V
The Attempt at a Solution
Ca+Cb= Qtotal/480
Qtotal/2=Qa initial
because they have the same capacitance
Ca=kQa final/480
Qa final- Qa initial = Change in Qa
Any help would be greatly appreciated.
