Consider the following circuit. As shown, lossy current source drives 1Kohm load by means of a voltage divider circuit. It is desired to have 5mA flow through the load. R1 and R2 can be assigned any value.
Part One: What is the smallest value that R2 can have?
Part Two: What is the largest value that R1 can have?
This solution is provided in approximately 344 words. It uses equations for voltage and current, as well as Kirchhoff's Current Law and information about resistors in parallel to solve for resistance.
