1. The problem statement, all variables and given/known data The circuit parameters are: R = 60 Ohms, L = 5 mH, C = 40 microFarads, and e= 120 V. Initially the switch has been closed for a long time. At t=0 the switch is opened. What is t1, the first time greater than or equal to 0, that the current through the inductor is equal to zero? a)t1=0 b)t1=2.11 ms c)t1=0.70 ms 2. Relevant equations 3. The attempt at a solution I really have no idea how to go about this question. Can someone help please?
