1. The problem statement, all variables and given/known data Here is the problem: 2. Relevant equations Typical RL circuit equations. 3. The attempt at a solution My main question with this problem is figuring out what to do with the third resistor, the one on the right. Initially, I thought of using RL circuit equations with the left circuit, but I don't know how to adjust that solution for the rightmost resistor. Please help me move past this step, thank you!
