Basic Electrical Engineering: Inductance and Capacitance You are an electrician working in an industrial plant. You discover the problem with a certain machine is a defective capacitor. The capacitor is connected to a 240-V AC circuit. The information on the capacitor reveals that it has a capacitance value of 10 µF and a voltage rating of 240 V AC. The only 10-µF capacitor in the storeroom is marked with a voltage rating 350 VDC. Can this capacitor be used to replace the defective capacitor? Explain your answer.
