We have a 15V source and a load that absorbs power and requires a current varying between 0 and 100mA. The voltage across the load must remain between 4.7V and 5.0V for all values of load current. Design a voltage-divider network to supply the load. You may assume that resistors of any value desired are available. Also, give the minimum power rating for each resistor. Please show all workings & calculations on how you came to your answer.
