A series RL circuit wid(s4wr*/q bsq-cv,k yth inductz h0 z6wnud4)fance L and resistance R is connected to an $emf$. After a period of time, the current reaches a final value of 2.0 A. A second series circuit is identical except that the inductance is 2L. When it is connected to the same $emf$, what will be the final value of the current?
A. $0.50 \; A$
B. $1.0 \; A$
C. $2.0 \; A$
D. $4.0 \; A$
