Question

Two parallel plate capacitors are connected in series. Both capacitors have square plates with each side measuring 8 cm. For capacitor 1, the plates are separated by 4 mm, for capacitor 2, they are separated by 8 mm. a) What are the capacitances of capacitor 1 and 2? Make sure you put them in units of picoFarad (1 pF = 10^(-12) F) C1 = C2 = b) What is the equivalent capacitance of this combination? Ceq = c) This combination is connected to a 12V battery. What is the charge on each of the capacitors? Q = d) With the 12V battery still connected, what are the voltages across capacitor 1 and capacitor 2? V1 = V2 = e) The battery is now disconnected, leaving the two charged capacitors connected in series. Subsequently a dielectric with dielectric constant K=5 is inserted into capacitor 2. What are the resulting voltages across capacitors 1, 2 and the combination now? V1 = V2 = Vtot =
