1. The problem statement, all variables and given/known data 2. Relevant equations V=IR 3. The attempt at a solution This problem is really confusing me. For VL(0-) and IL(0-), the voltage and current when t<0, wouldn't both those values just be 0? the 0- means before the switch is closed right? So before it is closed the right branch does nothing right? So It only has a current and voltage when you close the switch right? if so I found that the voltage VL would be the same as the voltage across the 10 ohm to the left of it, which is just a voltage divider giving me an value of 60V. If that is correct how can I find the current? Can I just say i=60V/10ohms and that would give me my current?
