DC-DC converter. You have 10 capacitors, each 1F. If you charge them in parallel from a 5V power supply, and then disconnect them and reconnect them in series:
a. What is the equivalent capacitance seen by the power supply while charging?
b. What is the equivalent capacitance of the series combination?
c. What is the voltage across the equivalent series capacitor?
d. How much charge can the series combination deliver to a load (such as a resistor) before the voltage drops by 10%?
e. Assume that you have a bunch of switches that let you change between the parallel and series configurations quickly, and that the switching time and charging time are negligible. If you charge and discharge 10 times per second, what is the average current that you would deliver to a load with the constraint from part d?
