(adsbygoogle = window.adsbygoogle || []).push({}); 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?
