The two parallel plate capacitors (C1 and C2) are initially charged by an external power source and the power source is disconnected later, leaving the two capacitors charged as seen in the figure. The capacitor C1 has dielectric material between its parallel plates. The length of the two parallel plate capacitors are the same. The distance between the parallel plates of the capacitors are also the same. However the width of C1 is 2a whereas the width of C2 is a. The amount of charge stored in C1 is Q1 = 10q. It is also observed that the amount of charge stored in C2 becomes Q2 = 4q if the dielectric material in C1 is removed (and replaced by air). What is the dielectric constant of the dielectric material that is used in C1?

You find that a 25-F capacitor connected to 480 VAC is defective. The storeroom has no capacitors with a 480-VAC rating. However, you find two capacitors rated at 50 F and 370 VAC. Can these two capacitors be connected in such a manner that they can replace the defective capacitor? If yes, explain how they are connected and why the capacitors will not be damaged by the lower voltage rating. If no, explain why they cannot be used without damaging the capacitor.
