An inductor (L = 0.03H) and a resistor (r = 0.15 kW) are connected in series to a battery of 15V EMF in a circuit shown below. The key K1 has been kept closed for a long time. Then at t = 0, K1 is opened and key K2 is closed simultaneously. At t = 1ms, the current in the circuit will be: (e5 ≅ 150)
0.67 mA
