- 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?

- Which of the following is true when charging a capacitor using a DC source? Current will flow due to the DC source and will charge the capacitor. Once the capacitor is fully charged, it has to be removed from the circuit it will not exceed the voltage of the source to avoid short-circuiting. Since capacitors behave as open circuits when a DC source is applied, there will be no charging current. The charging will happen due to KVL where the voltage of the source will be charged to the capacitor. Current will flow due to the DC source and will charge the capacitor. Once the capacitor is fully charged, it will act as if it is an open circuit. The answer cannot be found on the other choices.Original Schematic and OrCAD Schematic: The input primary voltage is 250V, frequency 50 Hz, primary inductance setting is 2000H and secondary inductance is 10H and voltage peak to peak ripple is approximately equal to 92mv.
