Table for pyrex glass values included

Consider the following circuit. Assume all wires are 0.20 mm diameter copper wires and that the battery is ideal: 12 µF 6 µF 12 V 6 µF 12 µF What is the equivalent capacitance for the circuit? а. b. What is the charge on each capacitor and the voltage across each capacitor? с. How much energy is stored when all the capacitors are fully charged? If there is a total of 20 cm of wire used in the circuit, what is the total resistance in the circuit. d. Suppose that once the capacitors are fully charged, they are disconnected from the battery, and the wires are then connected to each other forming a complete circuit. What is the maximum current that will flow in the wire? Does this current increase with time, decrease with time or remain steady? Explain.
