You are a journeyman electrician working in an industrial plant. Your task is to connect an inductor to a 480-V, 60-Hz line. To determine the proper conductor and fuse size for this installation, you need to know the amount of current the inductor will draw from the line. The nameplate on the inductor indicates that it has an inductance of 0.1 H. An ohmmeter reveals that it has a wire resistance of 10 . How much current should this inductor draw when connected to the line?
You are an electrician working in an industrial plant. You discover that the problem with a certain machine is a defective capacitor. The capacitor is connected to a 240-volt AC circuit. The information on the capacitor reveals that it has a capacitance value of 10 mF and a voltage rating of 240 VAC. The only 10-mF AC capacitor in the storeroom is marked with a voltage rating of 350 WVDC. Can this capacitor be used to replace the defective capacitor? Explain your answer.

The circuit shown in the attached image contains a voltage source with emf ε = 2.99 V, a resistor with resistance R = 135 kΩ, and a capacitor with capacitance C = 612 nF. When switch S is set to position a, the three circuit elements are in series. When the switch is in position b, the battery is excluded from the circuit. The switch is initially moved to position a, where it remains for a sufficiently long time that the capacitor is fully charged. The switch is now moved to position b. What is the magnitude of the instantaneous current, in amperes, through the resistor the instant the switch makes contact with terminal b? With time meausred the instant that switch S is closed in position b, calculate the time, in seconds, when the charge on the capacitor is one-half of its maximum value. Calculate the current through the resistor, in amperes, at time t = 155.5 ms after the switch is closed in position b.

Basic Electrical Engineering: Inductance and Capacitance You find that a 25-µF capacitor connected to a 480 V AC is defective. The storeroom has no capacitors with a 480 V AC rating. However, you find two capacitors rated at 50 µF and 370 V AC. Can these 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 damage to the capacitor.
