The battery shown in the figure is ideal. The values are \( \varepsilon=10 \mathrm{~V}, R=5 \Omega, L=2 \mathrm{H} \). Initially the current in the inductor is zero. The current through the battery at \( t=2 \mathrm{~s} \) is
(a) \( 12 \mathrm{~A} \)
(b) \( 7 \mathrm{~A} \)
(c) \( 3 \mathrm{~A} \)
(d) None of these
