10.A 100-µf capacitor is connected in series with a 150-volt voltmeter that has a resistance of 1,000 ohms per volt. (a) Calculate the reading on the voltmeter at the instant when t equals the time constant following the closing of the switch that impresses 120 volts on the circuit. (b) After the capacitor is completely charged, it is discharged across the resistance of the voltmeter. What will be the reading of the voltmeter 5 and 7 sec after the capacitor starts to discharge?

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.
