The series circuit shown in the figure contains an ideal battery with a constant terminal voltage $V _ { \mathrm { B } } = 60 \mathrm {~V}$, an ideal inductor $L = 50 \mathrm { H }$, a resistor $R = 11 \mathrm { ohm }$ resistor, and a switch $\mathrm { S }$. Initially, the switch is open, and there is no current in the inductor. At time $t = 0 \mathrm {~s}$, the switch is suddenly closed. What is the current in the circuit $4.09 \mathrm {~s}$ after closing the switch?

A) $2.7 \mathrm {~A}$
B) $2.2 \mathrm {~A}$
C) $4.3 \mathrm {~A}$
D) $5.5 \mathrm {~A}$
E) $3.2 \mathrm {~A}$
