We connect a 6 uF capacitor to the terminals of a 12 V battery, leaving it for a long time. Once the capacitor is fully charged, we remove the 12 V battery. Next, we connect the positive plate of the capacitor to the positive terminal of a 6 V battery, and the negative plate of the capacitor to the battery's negative terminal. At the moment the capacitor is connected to the 6 V battery, draw the new circuit. Indicate which plate of the capacitor is positive/negative and the direction of current flow, Calculate the current in the circuit or explain why you can't if it's not possible. Either way, give some qualitative description of what happens. Hint: where is the resistance in a DC circuit without a resistor?

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.
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.
