In Figure, after switch S is closed at time t = 0, the emf of the source is automatically adjusted to maintain a constant current i through S. a)Find the current through the inductor as a function of time. b)At what time is the current through the resistor equal to the current through the inductor?

The figures below show six circuits which consist of identical ideal batteries, resistors, and inductors. All of the switches are closed at the same time.  Rank the circuits based on the current through the battery immediately after the switch is closed. Rank from largest to smallest. To rank items as equivalent, overlap them.
