A capacitor consists of two metal plates each 500 × 500 mm² and spaced 6 mm apart. The space betweenthe metal plates is filled with a glass plate of 4 mm thickness and a layer of paper of 2 mm thickness. Therelative primitivities of the glass and paper are 8 and 2 respectively. Neglecting the fringing effect, thecapacitance will be (Given that = 8.85 x 10-12F/m)

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.
