Question

What is the current flowing through the battery immediately after the switch is closed? Use the following data: EMF = 18.5 V, R1 = 83.0 ?, R2 = 29.0 ?, L = 28.0 mH.

What is the current flowing through the battery a long time after the switch has been closed?

Explanation / Answer

After a long time the switch is closed, the curretn flow in the inductor is maximum. So, the current flow in the battery should be zero.
