An inductor \( (\mathrm{L}=0.03 \mathrm{H}) \) and a resistor \( (\mathrm{R}=0.15 \mathrm{k} \Omega) \) are connected in series to a battery of \( 15 \mathrm{~V} \) EMF in a circuit shown below. The key \( \mathrm{K}_{1} \) has been kept closed for a long time. Then at \( t=0, \mathrm{~K}_{1} \) is opened and key \( \mathrm{K}_{2} \) is closed simultaneously.
At \( \mathrm{t}=1 \mathrm{~ms} \), the current in the circuit will be : \( \left(\mathrm{e}^{5} \cong 150\right) \)
(a) \( 6.7 \mathrm{~mA} \)
(b) \( 0.67 \mathrm{~mA} \)
(c) \( 100 \mathrm{~mA} \)
(d) \( 67 \mathrm{~mA} \)
