You have button-type cells in your disposal as given below: Design a power supply for an IPod meeting the following requirements: When the IPod is turned ON it requires 32.5 mA current. The open circuit voltage of the power supply must be 10 V and when connected to IPod the voltage at the terminal should be 8.8 V. Use any combination of the available batteries, as many cells as needed. Show the structure and internal connections of the resulting power supply battery .
