Hi! I’m here again. Always the same: Professor doesn’t reply to my emails, I work full time, I can’t attend lessons.

I’m asked to find the current through the inductor. I’m still studying, I make errors, be kind with me please. This is my attempt.

Circuit for t < 0

Reducing it to:
1_2.png

Circuit for t > 0 (infinity)

Circuit for t = 0+

Am I right? Am I on the right way? How can I better understand this kind of exercise?

Thank you all in advance
