Question

In the circuit diagram shown

time constant is L/R
time constant is 2L/R
steady state current in inductor is $2 ε / R$
steady state current in inductor is $ε / R$

The correct answer is: time constant is L/R

Since the other resistance is attached parallel to the battery hence the time constant of the circuit will be L/R . At steady State the inductor offers zero resistance have hence at that time current in inductor will be E/R .
