You are working in an industrial plant. You have been instructed to double the capacitance connected to a machine. The markings on the capacitor, however, are not visible. The capacitor is connected to 560 volts and an ammeter indicates a current of 6 amperes flowing to the capacitor. What size capacitor should be connected in parallel with the existing capacitor? What is the minimum AC voltage rating of the new capacitor? What is the minimum DC voltage rating of the new capacitor? What is the minimum KVAR size that can be used in this installation?
An inductor has a current flow of 3 amperes when connected to a 240-volt, 60-Hz power line. The inductor has a wire resistance of 15 . What is the Q of the inductor?
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.

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.

You have the task of ordering a replacement inductor for one that has become defective . The information on the nameplate has been painted over and cannot be read . The machine that contains the inductor operates on 480 V at nameplate has been painted over also . A clamp - on ammeter indicates a current a frequency of 60 Hz. Another machine has an identical inductor in it , but its the machine that is still in operation . After turning off the power and locking out of 18 A , and a voltmeter indicates a voltage drop across the inductor of 324 V in the panel , you disconnect the inductor in the operating machine and measure wire resistance of 1.2 with an ohmmeter .
