Engineering Voltage/Current of inductor and capactiors 2nd order circuits

AI Thread Summary
The discussion centers on understanding the voltage across an inductor in a second-order circuit, specifically why it registers 3.816V despite having a current of 0A. Participants are encouraged to share their calculations and apply Kirchhoff's Current Law (KCL) or Kirchhoff's Voltage Law (KVL) to clarify the situation. The inquiry emphasizes the importance of analyzing circuit behavior at the moment just after a switch is closed (t=0+). Providing detailed equations and solutions is essential for resolving the confusion regarding the inductor's voltage. The conversation aims to deepen comprehension of inductor behavior in transient conditions.

Question 4 on the link.

I understand why the top inductor to the left has i = 0A but I don't understand why it has a voltage of 3.816V, can anyone care to explain?

When you work out the voltage across the inductor at t=0+, what do you get for the voltage? Can you show us your KCL or KVL equations and your solution for the inductor voltage at t=0+?
