An \( L R \) series circuit has \( L=1 \mathrm{H} \) and \( R=1 \Omega \). It is connected across an emf of \( 2 \mathrm{~V} \). Then
(a) The maximum rate at which energy is stored in the magnetic field is \( 1 \mathrm{~W} \)
(b) The maximum rate at which energy is stored in the magnetic field is \( 2 \mathrm{~W} \)
(c) The current at that instant is \( 1 \mathrm{~A} \)
(d) The current at that instant is \( 2 \mathrm{~A} \)
