A voltage divider is to be built to give a 5V output from a 12V input. The nominal load is 5 W. Design a divider to provide 5 V ± 5% for loads ranging from 3W to 5W, assuming that the input line is perfectly regulated at exactly 12 V. What is the no-load output? What is the efficiency at nominal load.
