How Does Switching Impact Current Flow in an RL Circuit?

The switch in the figure is open for a very long time and then closed at t = 0. What is the current through R1 immediately after the switch is closed? ( Use V = 3.5 V, R1 = 848 , R2 = 548 , L = 7.2 mH )
After the switch has been closed for a long time what is the current through R1?
After the switch has been closed for a long time what is the current through R2?

Hi Havoc0040. Welcome to Physics Forums.

What is your question about this problem? What have you already tried?

The switch is now opened. What is the current through R11 immediately after the switch is opened? this is my question i thought it was 0 but that's not right
