1. The problem statement, all variables and given/known data Design a “smart” branch with resistors and a diode pair such that the branch resistance drops if the voltage applied on the two ends of the branch is too high, and vice versa, (i.e., the branch resistance increases if the voltage applied on the two ends of the branch is too low). 2. Relevant equations 3. The attempt at a solution Could Anyone explain to me what is this question asking me to do? Or like any hints as to how should i solve this type of question?
